A restored Gilded Age mansion just off Fifth Avenue is listed at $68 million. While many of New York’s Gilded Age houses were demolished or converted, this one remains an intact single-family residence.

A seven-story Beaux-Arts mansion — once home to a Russian prince and later restored from a shell — has come to market at $29.75 million.

Originally built in Amsterdam in the 17th century, the property was dismantled and rebuilt twice in New York City, and underwent a “gothic fantasy makeover” under British-born architect Frederick Sterner in 1910.

With its handcrafted Italian limestone facade and classical detailing, this New York townhouse offers plenty of curb appeal, along with a coveted address between Madison Avenue and Park Avenue.

In the heart of Manhattan's prestigious Upper East Side near Central Park, 4 East 79th Street stands as a tribute to history, a testament to restoration, and an embodiment of architectural elegance.
