During the Gilded Age, Newport, Rhode Island, transformed from a quiet summer retreat into a glittering stage for America’s “industrial royalty.” At the center of this transformation was the Vanderbilt family and the houses they built and owned. While Commodore Cornelius Vanderbilt built the family’s initial fortune, it was the eight children of his eldest son, William Henry Vanderbilt, who truly helped give shape to the Gilded Age. Four of the eight children built or expanded homes in Newport and these extraordinary structures are landmarks not just in the City-by-the-Sea, but are all recognized landmarks on a national level.
The Breakers: The Epitome of the Gilded Age

The Breakers (Interior)
In 1893, Cornelius Vanderbilt II, the eldest of the eight children, commissioned the architect Richard Morris Hunt to design a replacement for a Peabody & Sterns wooden mansion that had burned down. The result was The Breakers, a 70-room Italian Renaissance-style palazzo inspired by the 16th-century palaces of Genoa and Turin.
The house was intended to be fireproof, constructed using steel, brick, and limestone. Its design impact cannot be overstated; it remains the ultimate symbol of the Vanderbilt era, representing a moment when American wealth sought to rival the centuries-old aristocracy of Europe. The Great Hall, with its 50-foot ceilings, served as a stage set for social standing, signaling that the Vanderbilts had truly arrived. It is still one of the largest private houses to ever be built in the United States and is owned and open to the public by the Preservation Society of Newport County (PSNC).
William Henry’s second child and eldest daughter was Margaret Louis Vanderbilt Shepard. Unlike her siblings, she chose to stay close to New York and lived in a double mansion there with her family and that of younger sister, Emily. She also had a McKim, Mead and White-designed mansion in Scarborough, NY called Woodlea, which has now been adaptively converted into a gracious clubhouse.
Marble House: A Social Revolution

The third child, William Kissam Vanderbilt, commissioned Marble House as a 39th-birthday gift for his wife, Alva. This house was also designed by Richard Morris Hunt, the leading architect of the early Gilded Age. After Alva divorced her first husband, she married Oliver Belmont and moved across Bellevue Avenue to Belcourt, but she kept Marble House for entertaining and eventually commissioned the Chinese Tea House so that the grounds could be used for gatherings supporting women’s suffrage. The house and its 500,000 cubic feet of glimmering white marble also eventually became the property of the PSNC and is open year-round for visitation and rental for special events.

Architecturally, Marble House was one of the early Newport Mansions to depart from the Queen Anne and Shingle Style “cottage style” of earlier Gilded Age, Newport summer homes, leaning instead toward the Beaux-Arts grandeur of the Petit Trianon at Versailles. Its design impact also extended far beyond the community, and it has been recognized nationally for is grand European-styled elegance as a National Historic Landmark, the highest honor the secretary of the interior can bestow.
Stoneleigh: A mansion that has had many owners

Stoneleigh, Newport
Emily Thorn Vanderbilt Sloane, the fourth child, shared the Vanderbilt double mansion in New York on Fifth Avenue, and had her primary, summer estate in Massachusetts but she and her husband also purchased 2 mansions in Newport called Stoneleigh in 1881, located on Narragansett Avenue across from the Oakwood estate. In 1927 it became a Carmelite nunnery before becoming the St Paul’s Benedictine priory in 1962. The house returned to private hands, and remains privately owned to this day, and is an ideal candidate for renovation.
Vinland: A Diverse Architectural Expression

The fifth child was Florence Adele Vanderbilt Twombly. Rather than building a new house like her elder brothers she purchased Vinland, the Romanesque and English Manorial styled estate in Newport from the Lorillard family. She expanded the structure and under Florence’s direction, the house was transformed into a massive Romanesque Revival masterpiece. Today, Vinland serves as McAuley Hall as part of the Salve Regina University campus, illustrating how many large private estates were eventually adaptively reused as educational buildings.
Rough Point: A Mansion in Transition
The sixth child, Frederick William Vanderbilt, also sought a slightly more “understated” (at least by Vanderbilt standards) retreat in Newport, and commissioned Rough Point, originally designed in the English Manorial style by Boston firm of Peabody & Stearns. The building utilized red sandstone and granite to mimic an English manor house. Located at the very end of Bellevue Avenue, overlooking the Atlantic Ocean, this house feels far more alone and freer from encroaching structures than the majority of mansions along this grand avenue. Unlike the French-inspired palaces of his other brothers, Frederick’s home capitalized upon the rugged beauty of the Newport coastline. The house later became famous as the home of heiress Doris Duke, who preserved (but expanded) much of its original Gilded Age character. Since her death, this house has been operated by the Newport Restoration Foundation, and is still open to visitation during the summer, which is when its past occupants used this 105-room home.

The seventh child, Eliza Osgood Webb, was another Vanderbilt who preferred a quieter life than Newport offered in the summertime and, in addition to her family’s New York manse, built the famed Shelburne Horse Farm in Shelburne Vermont. This extraordinary estate, designed by noted architect Robert H. Robertson, now operates as a 1,400-acre agrarian educational facility and inn.
The eighth and youngest child, George Washington Vanderbilt, not to be outdone by his older siblings, commissioned Richard Morris Hunt to design the Biltmore Estate on 8,000 acres in the mountains of Asheville, North Carolina. This Châteauesque mansion is reminiscent of the European structures that Hunt designed for his elder brothers but was set on a vast rural site similar to the estates of his older sisters. At 178,000sf and 250 rooms, Biltmore is still the largest private house ever to be constructed in the United States. Extraordinarily, the house is still operated and opened for public visitation by descendants of the original owner.
The Lasting Legacy
The impact of these Newport “summer cottages” designed for or expanded by the Vanderbilt siblings, still echoes through time and stretches far beyond various location. The Vanderbilt children’s obsession with creating a grandeur never seen before in the United States turned Newport into a treasure trove of Gilded Age luxury and craftsmanship that continues to inspire people until the present day. However, the maintenance of such estates became impossible for subsequent generations after the introduction of the federal income tax and the Great Depression, and so they became examples of how enormous and stately houses could be transformed for new purposes.

Today, through the efforts of the Preservation Society of Newport County, Salve Regina University, and the Newport Restoration Foundation, these grand structures continue to help drive the region’s tourism economy and identity. Their existence serves as a physical reminder of a period of unprecedented economic growth, extreme social stratification, and the birth of American Beaux-Arts architecture.
