The name ‘Oheka’ comes from the owner’s initials Otto Hermann Kahn. During its heyday, the estate employed 126 servants and hosted legendary parties attended by Hollywood stars and royalty. After falling into disrepair, it underwent a $30 million restoration.

Alexander Hamilton married Elizabeth Schuyler in the mansion’s parlor in 1780, connecting this property to one of America’s most fascinating founding figures. The house features 18th-century furnishings, portraits, and decorative arts that reflect the refined taste of Albany’s elite during this pivotal era.

Tragedy struck when Louise suddenly died in 1904, causing a devastated Boldt to immediately halt all construction. For 73 years, the unfinished castle stood abandoned to the elements until the Thousand Islands Bridge Authority purchased it and began restoration work.

13. Oakhurst: An Arts and Crafts Jewel in the Catskills

Hidden among the Catskill Mountains is Oakhurst, a spectacular Arts and Crafts style mansion that represents a departure from the classical designs favored by many Gilded Age millionaires. Built in 1905 for industrialist Horace Lamberton, this stunning retreat embraces natural materials and craftsmanship rather than European grandeur.
Massive stone fireplaces anchor interior spaces filled with hand-crafted furniture, stained glass windows, and exposed wooden beams. Unlike the formal gardens of other mansions, Oakhurst’s grounds blend seamlessly with the surrounding forest, reflecting the Arts and Crafts movement’s celebration of nature and simplicity.

Built in 1889 for railroad executive Collis P. Huntington, this Colonial Revival mansion brought Newport-style opulence to the shores of Long Island Sound.
The 40-room mansion features hand-carved woodwork, imported marble, and massive windows capturing spectacular water views. Though called a “cottage” in the understated language of the wealthy, Hunter House rivals European palaces with its grand ballroom, formal dining room seating 30 guests, and extensive servant quarters.
After serving as a hospital during World War II, the property became a conference center and hotel. The mansion’s original boathouse, stables, and gate lodge remain intact, providing a glimpse into the lifestyle of New York’s industrial aristocracy who created private compounds along the sound.
16. Marble House: Alva Vanderbilt’s Architectural Statement

Completed in 1892 at a cost of $11 million (equivalent to over $300 million today), this mansion was intended as Alva’s “temple to the arts” and her ticket to social acceptance.
The Gold Ballroom remains the mansion’s most spectacular space, covered in gold leaf and designed to outshine every other home in New York. Interestingly, Alva used the house for only four years before divorcing William K. Vanderbilt and later becoming a prominent women’s suffrage activist.

Mrs. Oelrichs, who married into a prominent New York shipping family, hosted famous “white parties” where guests dressed entirely in white and danced until dawn. The mansion’s heart-shaped staircase and ocean views provided perfect backdrops for society photographers documenting these lavish events.
Film buffs might recognize Rosecliff from “The Great Gatsby” (1974) and “True Lies.” Though located in Newport, Rhode Island, the mansion represents the extravagant lifestyle of New York’s wealthy families who maintained multiple homes designed for specific social seasons and functions.
18. The Breakers: Cornelius Vanderbilt II’s Summer “Cottage”

The Breakers stands as the grandest of all Vanderbilt homes, a 70-room Italian Renaissance-style palazzo built as a summer residence for Cornelius Vanderbilt II, chairman of the New York Central Railroad. Completed in 1895 at a cost of $7 million (over $200 million today), this architectural marvel sits on 13 acres of oceanfront property.
Every surface inside showcases extraordinary craftsmanship – platinum wall panels, mosaics from Italy, and ceilings painted by European artists transported to America specifically for this project. The Great Hall rises 50 feet with a massive skylight illuminating marble imported from Africa and Europe.

19. Frick Mansion: From Private Home to World-Class Museum

Henry Clay Frick, the controversial steel magnate and art collector, built this magnificent Beaux-Arts mansion on Fifth Avenue directly across from Central Park. Completed in 1914, the limestone mansion was designed from the beginning to eventually become a public museum housing Frick’s extraordinary art collection.
Unlike many Gilded Age mansions designed primarily to impress, Frick created intimate rooms scaled for displaying his masterpieces by Rembrandt, Vermeer, and Gainsborough. The central garden court with its fountain and skylight provides a peaceful contrast to the bustling city outside.
After Frick’s death in 1919, the mansion was transformed into the Frick Collection, one of New York’s most beloved museums. The family’s private living quarters upstairs remained closed for decades but have recently been renovated and opened to the public, revealing how the Frick family lived among their treasures.
20. Morris-Jumel Mansion: Manhattan’s Oldest Surviving House

Perched on one of Manhattan’s highest points sits the Morris-Jumel Mansion, a remarkable survivor from 1765 when much of the island remained farmland. British colonel Roger Morris built this Georgian mansion as a summer villa, taking advantage of breezes and spectacular views stretching from the Harlem River to New York Harbor.
During the Revolutionary War, George Washington used the house as his headquarters during the Battle of Harlem Heights. Later, the controversial French merchant Stephen Jumel and his wife Eliza purchased the property, adding Federal and Empire style elements that remain today.
After Stephen’s death, Eliza briefly married former vice president Aaron Burr in the mansion’s parlor. The house became a museum in 1904, preserving period furnishings, decorative arts, and personal items from its fascinating residents. Today it stands as Manhattan’s oldest surviving residence, offering a rare glimpse into New York’s colonial past.
21. Merchant’s House Museum: Preserved Perfection in NoHo

Time stands perfectly still inside the Merchant’s House Museum, New York City’s most intact 19th-century home. Built in 1832 and occupied by the prosperous Tredwell family for nearly 100 years, this red-brick row house offers an unparalleled glimpse into the domestic life of New York’s merchant class.
Unlike mansions built by industrial tycoons, this elegant home represents the lifestyle of successful but not extravagantly wealthy New Yorkers. The interiors remain virtually unchanged since 1865, with original furnishings, decorative arts, clothing, and personal possessions still in place.
Many believe the house remains occupied by more than just visitors it’s considered New York’s most haunted building, with numerous reports of encounters with Gertrude Tredwell, who was born in the house in 1840 and never left until her death in 1933. The perfectly preserved Greek Revival interiors make this museum an architectural time capsule.
