Minnesota’s historic mansions are concentrated in neighborhoods like St. Paul’s Summit Avenue and Minneapolis’s Lowry Hill, where the state’s industrial elite left an indelible architectural mark. Summit Avenue, often referred to as one of the longest stretches of preserved Victorian-era homes in the country, offers an eclectic mix of styles.
The James J. Hill House, built in 1891, dominates the avenue with its Romanesque Revival massing. Constructed from Minnesota limestone, its sheer scale and attention to detail set the tone for the neighborhood. Lowry Hill in Minneapolis, meanwhile, presents a different architectural scene. Here, the Swan Turnblad Mansion, completed in 1908, stands out with its Beaux-Arts elegance, featuring turrets, dormers, and ornate stonework. Built by a Swedish newspaper magnate, it contrasts with the neighborhood’s more subdued Prairie School and Colonial Revival homes, showcasing a mix of old-world grandeur and early 20th-century ambition.
These neighborhoods serve as open-air museums of Minnesota’s economic and cultural development, where each property reflects the aspirations and resources of its builders, forming a unique architectural dialogue across time and space.
15. Swan Turnblad Mansion – Minneapolis

The Turnblad Mansion, now the home of the American Swedish Institute in Minneapolis, is a châteauesque giant built between 1904 and 1908 during Park Avenue’s brief tenure as the city’s “Golden Mile.” Commissioned by Swedish-American newspaper magnate Swan Turnblad, the mansion sprawls across six city lots and boasts 33 rooms, each meticulously crafted to reflect a mix of global styles. Minneapolis architects Christopher Boehme and Victor Cordella were charged with realizing Turnblad’s vision, creating an Indiana limestone masterpiece decorated with gargoyles, decorative lions, and fossils embedded into its stonework — a material famously shared with the Empire State Building.
The mansion’s design channels French Renaissance influences, with steeply pitched rooflines, a dominant turret, and intricate stone carvings. The interior features Gustavian elegance alongside Moorish flair. Eleven ornate kakelugnar (Swedish tile stoves) punctuate the rooms, serving both as functional heaters and cultural artifacts. The Grand Hall, illuminated by the Visby Window, stands as the architectural and cultural heart of the home.
Despite its grandeur, the Turnblad family barely lived there, decamping to an apartment across the street by 1915. In 1929, the mansion became a museum — a reflection of Turnblad’s desire to preserve Swedish heritage in the Midwest, transforming his home into a cultural legacy.
14. LeDuc Historic Estate – Hastings

The William G. LeDuc House, a Gothic Revival gem in Hastings, Minnesota, stands as a rare and remarkably intact example of Andrew Jackson Downing’s architectural vision. Built between 1862 and 1866, the house reflects the aspirations of its owner, William Gates LeDuc, a Civil War veteran, attorney, and later U.S. Commissioner of Agriculture under President Rutherford B. Hayes. Inspired by Downing’s influential Cottage Residences, the design incorporates steep gables, pointed arches, and a symmetrical elegance.
The estate, which includes a residence, carriage barn, and ice house, showcases Downing’s belief in integrating architecture with the surrounding landscape. The LeDucs’ property, set near Vermillion Falls, features an understated grandeur, from the intricate wood detailing to the intentional use of light and proportion in the home’s layout. The site embodies the era’s blending of function and aesthetics, a hallmark of Carpenter Gothic design.
13. Cedarhurst Mansion – Cottage Grove

The Cordenio Severance House, known as Cedarhurst, is a Neo-Classical landmark in Cottage Grove, Minnesota, with roots stretching back to its humble beginnings as a post-Civil War farmhouse. Transformed into a grand summer estate for St. Paul attorney Cordenio Severance between 1911 and 1917, the mansion is a 26-room showpiece, significantly shaped by architect Cass Gilbert. Gilbert, famous for designing the Minnesota State Capitol and the U.S. Supreme Court Building.
Cedarhurst boasts two commanding columned porticos, a 100-foot veranda, and an English rose garden. Inside, the mansion’s formal ballroom features a pipe organ. Three fireplaces punctuate the interior, while the library has hosted figures ranging from presidents Roosevelt, Taft, and Coolidge to early meetings of the CIA.
12. Burbank-Livingston-Griggs House – Saint Paul

The Burbank–Livingston–Griggs House on Summit Avenue in Saint Paul is a masterful example of mid-19th-century Italianate architecture, completed in 1863. Designed by Otis L. Wheelock of Chicago, the mansion is constructed of grey limestone quarried across the Mississippi River in Mendota. Its arched windows, bracketed cornice adorned with carved pendants, and a glass-enclosed cupola with a finial define the building’s stately silhouette. The polygonal bay windows and Corinthian columns supporting an entablature add layers of refinement, while its open floor plan incorporates oak and marble finishes, steam heat, and one of Minnesota’s first parquet floors.
The house, commissioned by James C. Burbank, was a beacon of luxury when Summit Avenue was still a rough oxcart trail. Burbank, a self-made entrepreneur, built his fortune on steamboats and stagecoaches, eventually shaping Saint Paul’s civic infrastructure through his roles in commerce and public office. The property’s location on a bluff provided commanding views of his growing empire.
Over the decades, the mansion evolved under successive owners, including Crawford Livingston and Mary Griggs, who left their own architectural and decorative marks. Livingston collaborated with Clarence H. Johnston Sr. to add stained glass and carved oak paneling. Later, Mary Griggs expanded the house with a two-story limestone addition and furnished it with entire rooms imported from European estates. Architects Magnus Jemne and Edwin Lundie meticulously fitted these antique interiors, while the basement gained a glass-walled Art Deco ballroom.
Donated to the Minnesota Historical Society in 1968, the house served as a museum before its conversion into apartments in 1996. Though its function has shifted, the Burbank–Livingston–Griggs House remains a vital landmark, encapsulating layers of architectural and cultural history.
11. James J. Hill House – North Oaks

The James J. Hill House in St. Paul, Minnesota, is a defining example of Richardsonian Romanesque architecture, completed in 1891. Designed by Peabody, Stearns, and Furber, with later contributions by Irving and Casson, the mansion’s structure is marked by its heavy limestone construction, a hallmark of the Romanesque style. The façade features rounded arches, rough-hewn stone blocks of varying sizes, and a strong horizontal emphasis.
The interior of the 36,000-square-foot mansion reflects a mix of functional innovation and aesthetic richness. The first floor showcases intricate hand-carved woodwork, particularly in the grand staircase, central hall, and formal dining room with a gold-leafed ceiling. The art gallery, designed to house Hill’s significant collection of paintings and sculptures, includes a built-in pipe organ.
Technologically advanced for its time, the house featured a hybrid lighting system of gas and electricity, though it lacked electrical outlets, as electricity was primarily for lighting. The design includes distinct spaces for public entertaining, private family quarters, and servant accommodations, each tailored to its function with attention to material and layout.
10. Comstock House – Moorhead

The Comstock House in Moorhead, Minnesota, is an elegant blend of Queen Anne and Eastlake architectural styles, designed by the Minneapolis firm Kees & Fisk and completed in 1883. Built for Solomon Comstock, a pioneering figure in Moorhead’s transformation into a thriving railroad town, the house is an example of late Victorian design in a rapidly developing frontier city.
The eleven-room structure ifeatures an asymmetrical façade, steep gables, and ornamental wood detailing, all hallmarks of the Queen Anne style. Eastlake influences are evident in the intricate spindlework, geometric patterns, and emphasis on craftsmanship throughout the home.
The Comstocks played an active role in Moorhead’s civic life, hosting library board meetings and women’s club gatherings. Strategically located in the Highlands addition of Moorhead, the house was positioned to avoid the floods that plagued the lower Points neighborhood near the Red River, where the family had previously lived.
9. Oliver G. Traphagen House – Duluth

The Oliver G. Traphagen House, also known as Redstone, is a striking example of late Victorian architecture in Duluth, Minnesota. Completed in 1892, this three-story residence was designed by its namesake, Oliver G. Traphagen, a leading architect of the city’s late 19th-century building boom. Constructed of locally sourced red sandstone with unadorned brickwork on the less-visible sides, the house is a creative blend of Richardsonian Romanesque elements with ornate Victorian detail.
Key features of the 9,200-square-foot house include its wraparound porch with carved stone balustrades, a soaring turret with intricate stonework, and a steep slate roof accented by dormers. Designed as a duplex, the house contains two nearly identical units, each with a parlor, sitting room, library, dining room, and bedrooms on the upper floors. The interior also includes 10 fireplaces and early dual-use gas and electric light fixtures.
Traphagen lived in the house with his family for only a few years before selling it to mining magnate Chester Congdon in 1897. After the Congdon family moved to Glensheen in 1908, the house transitioned into apartments in 1919. Over the 20th century, the house weathered neglect and significant structural changes but was revived in the 1980s when it was carefully restored.
The house suffered a devastating arson attack in 2014. Despite extensive damage, the Traphagen House remains structurally sound and an enduring symbol of Duluth’s architectural heritage.
8. Purcell-Cutts House – Minneapolis

The Purcell-Cutts House in Minneapolis, designed in 1913 by William Gray Purcell and George Grant Elmslie, is a quintessential expression of the Prairie School style of architecture. Built near Lake of the Isles for Purcell’s family, the house epitomizes the firm’s commitment to progressive design principles inspired by their mentor, Louis Sullivan. It is a carefully crafted response to the revivalist trends of the era, prioritizing modern living and harmony with the environment.
Key Prairie School features define the house, including its nearly flat roof, strong horizontal lines, and integration with the landscape. The structure is decorated with over 80 art-glass windows, which flood the interior with natural light while maintaining privacy, a hallmark of Sullivan’s “system of ornament.” The windows, along with custom stencils and furniture, create a cohesive aesthetic that blurs the line between decoration and structure. The open floor plan, a forward-thinking choice for residential design, creates a sense of spaciousness, emphasizing function over formality.
The Purcells lived in the home for only a few years before relocating, but subsequent owners preserved its architectural integrity. Bequeathed to the Minneapolis Institute of Art in 1985, the meticulously restored house now serves as a public museum, as an example of Prairie School innovation and craftsmanship.
7. Lind House – New Ulm

The John Lind House, built in 1887 in New Ulm, Minnesota, is a graceful Queen Anne residence designed by Frank B. Thayer of Mankato. Constructed at a cost of $5,000, the home exemplifies late Victorian architectural elegance, with its wrap-around porch, decorative spindlework, and commanding turret. Situated at the corner of Center and State Streets, the property was originally purchased by Alice Lind, wife of John Lind, in 1885, marking the beginning of its association with one of Minnesota’s prominent political figures.
During Lind’s tenure as a U.S. Congressman and later as Governor of Minnesota, the house was a hub of political and social activity. The spacious interior originally featured a built-in buffet, sliding doors, and an elaborate central staircase. In later years, the home underwent significant changes. Dr. George Reineke purchased it in 1908, converting it into two apartments by 1927. This remodeling removed several original features, including the staircase and dining room fireplace, and altered its layout. The Lind House Association initiated a restoration in 1985, returning the exterior to its original design while preserving and recreating key interior elements.
6. Alexander Ramsey House – Saint Paul

The Alexander Ramsey House, built between 1868 and 1872 in Saint Paul’s Irvine Park neighborhood, is a striking example of Victorian architecture meticulously designed by Monroe Sheire, a prominent early Minnesota architect. Once home to Alexander Ramsey, Minnesota’s first territorial governor and second state governor, the 15-room house remains one of the best-preserved Victorian residences in the United States. Constructed at a cost of nearly $41,000, the house reflects both Ramsey’s political prominence and the era’s technological advancements.
The home’s exterior features solid stone construction, typical of high Victorian style, while the interior boasts carved walnut woodwork, marble fireplaces, and crystal chandeliers. Innovations like hot water radiators, gas lighting, and running hot and cold water marked it as a cutting-edge residence for its time. Ramsey’s wife, Anna, furnished the home in lavish Renaissance Revival style, bringing two boxcars of furniture from New York’s A.T. Stewart Company Store.
The house remained in the Ramsey family until 1964, when it was bequeathed to the Minnesota Historical Society. Carefully preserved, it now operates as a museum showcasing original furnishings and artifacts, offering an authentic glimpse into 19th-century life.
5. Hubbard House – Mankato

The Rensselaer D. Hubbard House in Mankato, Minnesota, blends French Second Empire and Italianate styles. Built in 1871 and expanded in 1888, the house reflects the wealth and ambition of R.D. Hubbard, a businessman whose flour milling empire left a lasting mark on southern Minnesota. Designed by Silas Barnard, the mansion’s two-and-a-half-story main section features a mansard roof of colorful slate, while the Italianate addition adds a telescoped wing with refined proportions and Ionic-columned porch detailing.
Constructed with a cut-stone foundation and brick walls accented with Mankato stone, the house was among the first in the region to feature advanced amenities such as indoor plumbing, central heating, and electricity. Hubbard, hedging his bets on the future of electricity, installed lighting that could run on both gas and electric power. The interior features a grand oak staircase, three fireplaces with Brazilian onyx and Italian marble, and silk damask wall coverings in the parlor imported from Paris. A Tiffany chandelier hangs over the dining room.
Following its purchase by the Blue Earth County Historical Society in 1938, the house became a museum. A meticulous 20-year restoration, completed in 2009, returned the residence to its 1905 appearance, preserving its period gardens, original furniture, and historic charm. The adjacent Queen Anne-style carriage house, added to the site in 1977, houses antique vehicles, complementing the house’s interpretation of turn-of-the-century life.
4. Lund–Hoel House – Canby

The Lund–Hoel House in Canby, Minnesota, was built in 1891 for John G. Lund, a self-made millionaire and dynamic civic leader. The house underwent an extensive remodel in 1900, transforming it into the stately Victorian landmark that still dominates its corner of Highway 75 and 4th Street.
The architectural details are pure Queen Anne, with its asymmetrical façade, decorative gables, and elaborate wood trim. A wrap-around porch adds both visual balance and functional charm. The adjacent carriage house complements the residence, showcasing the practical elegance of late 19th-century domestic life.
John G. Lund, known as “Land” Lund for his success in real estate, was a driving force in the development of Yellow Medicine County. As a land speculator, banker, and mayor of Canby, his influence extended beyond the house’s walls. Following Lund’s death in 1908, the home became associated with his sister Mary Lund Hoel and her husband Reverend Olaf Hoel, adding another layer of local history to the property. Now preserved as a historic house museum, the Lund–Hoel House is maintained by dedicated volunteers who ensure its restoration adheres to original materials and methods.
3. Woodbury Fisk House – Minneapolis

The Woodbury Fisk House, built in 1869 in Minneapolis’ Marcy-Holmes neighborhood, is a standout example of Italianate architecture. Woodbury Fisk, a New Hampshire native, commissioned the house during his prosperous years as a hardware supplier to the lumber industry and later as a partner in Pillsbury, Crocker, and Fisk, the precursor to the Pillsbury flour empire.
Constructed from buff-colored brick atop a limestone foundation, the two-story residence reflects the ornate yet balanced design principles of the Italianate style, popular in the mid-19th century. Its L-shaped original wing and stylistically consistent rear addition — likely added shortly after the initial construction — emphasize both practicality and aesthetic cohesion.
Key Italianate elements include extended eaves supported by paired, scrolled brackets, a dentilated cornice, and hooded arch windows decorated with carved leaf details on the second floor. Though some arches have been infilled with modern rectangular windows, the house retains much of its historic integrity. Two porches, one open and one screened, feature elaborate arch supports with intricately carved spandrels and balusters, adding an air of craftsmanship to the exterior. The main entrance, composed of double doors crowned with a stained-glass transom, is framed by the detailed façade and shaded by mature mulberry trees.
2. Van Dusen House – Minneapolis

The George W. and Nancy B. Van Dusen House in Minneapolis is a grand expression of late 19th-century prosperity, built in 1891 for George Van Dusen, a pioneering figure in Minnesota’s grain industry. Situated in the Stevens Square neighborhood, the 12,000-square-foot mansion was designed by Orff and Joralemon in the Richardsonian Romanesque style, with additional French Renaissance influences that elevate its architectural complexity.
Constructed from pink Sioux quartzite quarried in Luverne, Minnesota, the mansion features a slate roof and soaring turrets topped with copper finials. Its Richardsonian Romanesque elements include massive stone arches and robust forms, while the steep roofs and slender turret nod to French Renaissance design. The interior is a showcase of eclectic design, blending Gothic, Tudor, Romanesque, French, and Elizabethan styles. Highlights include 10 fireplaces, carved woodwork, parquet floors, a tile mosaic entryway, and a grand staircase illuminated by large skylights.
The house’s unique features, such as I-beam construction reputedly designed to make it tornado-resistant and tunnels extending into the yard, reflect the Van Dusens’ concerns to safeguard their home after surviving a previous tornado.
A comprehensive restoration in the mid-1990s saved the property from demolition. Restored to its former glory, with modern updates for events and gatherings, the Van Dusen House now stands as one of Minneapolis’ most celebrated architectural landmarks and a popular venue for weddings and special events.
1. Gale Mansion – Minneapolis

The Gale Mansion, located in the Fair Oaks neighborhood of Minneapolis, is a stately example of Italian Renaissance Revival architecture, completed in 1912. Designed by Minnesota architect Ernest Kennedy, the house reflects the refined tastes of its original owners, Edward Chenery Gale and Sarah Belle Pillsbury Gale, prominent figures in Minneapolis society and arts patronage. Constructed from Bedford limestone, the home combines European elegance with early 20th-century technological sophistication.
The façade is characterized by symmetrical design, arched windows, and French doors that lead to a now-lost Italian garden. Inside, the first floor features oak parquet floors, a grand black walnut staircase, and eight ornate fireplaces. Modern conveniences for 1912 include a central vacuum system, an intercom, and a maze of laundry chutes. The Great Hall once housed a pipe organ and opened onto a terrace.
In 1947, the Minneapolis Branch of the American Association of University Women (AAUW) purchased the house, repurposing its spaces for meetings and events. Gale Mansion was listed on the National Register of Historic Places in 1977 as a preserved link to Minneapolis’s architectural and cultural heritage.
