In the late 19th century, Fifth Avenue in New York City transformed into a showcase of opulence as wealthy tycoons erected lavish mansions that rivalled the grandeur of European palaces. This stretch of what became known as “Millionaire’s Row” served as a backdrop to the city’s elite society, ushering in an era that would epitomise the Gilded Age.

The term “Gilded Age” refers to a period of dramatic economic growth and ostentation in the United States, primarily during the 1880s. During this time, affluent figures such as the Vanderbilts and the Astors spent vast sums on their residences, commissioning architects to design French châteaux and Italian palazzo-inspired homes. Today, HBO’s acclaimed drama, also titled “The Gilded Age,” illustrates this remarkable chapter in American history, albeit with a fictional twist.

However, this period of architectural splendour was relatively short-lived. The turn of the 20th century brought rising land values, increased estate taxes, and changing social dynamics, leading many of these grand homes to make way for high-rise apartment buildings. As a result, the iconic limestone facades that once adorned the streets began to disappear, even as their legacy continued to shape Manhattan’s identity.

One notable example of the opulent residences from this time is Petit Chateau, which was built for William K. Vanderbilt and his first wife Alva. Designed by the renowned architect Richard Morris Hunt and completed in 1882, the mansion was constructed from Caen stone and filled with European antiques. It also hosted the famous Vanderbilt Costume Ball in 1883, an event that catapulted Alva into the upper echelons of New York society. Following its sale to a developer in 1926, Petit Chateau was ultimately demolished, and today, a modern tower occupies its former site.
Adjacent to this, Cornelius Vanderbilt II’s mansion stood as one of the largest private residences in New York City at the time it was built. Located at the intersection of 57th Street and Fifth Avenue, it was surrounded by commercial developments by the 1920s, including the Plaza Hotel. Like many of the grand homes of the era, the mansion was sold in 1926 and later replaced by the Bergdorf Goodman department store. The only remnants of its grandeur, the ornate front gates, now reside in nearby Central Park.
The Astor family’s influence during the Gilded Age was also considerable, with Caroline Astor, wife of William Backhouse Astor Jr., possessing two homes along Fifth Avenue. One of these opulent residences featured a grand ballroom capable of hosting 1,200 guests. After Caroline’s passing in 1908, her son, John Jacob Astor, renovated the estate. However, his tragic death aboard the RMS Titanic in 1912 resulted in a complex inheritance scenario that led his new wife to relinquish the home. Ultimately, the property was sold to developers and now serves as the site for Temple Emanu-El.
Further up the avenue, the extravagance continued with the construction of William A. Clark’s mansion, informally dubbed “Clark’s Folly.” The so-called Copper King invested millions into this colossal residence at 77th Street, which boasted 121 rooms, multiple baths, art galleries, a swimming pool, and even an underground rail line for heating coal. Clark’s home, which took 14 years to complete, epitomised the extremes of wealth during this period. He passed away in 1925, and just two years later, the mansion was sold and subsequently demolished. In its place, a luxury condominium tower now rises.
While the architectural landmarks of the Gilded Age have largely vanished from Fifth Avenue, the allure of this brief but luxurious period remains palpable. The grandeur and excess of the era are not just echoes of the past but serve as a vivid reminder of how the economic ambitions and social aspirations of a few reshaped the cultural landscape of New York City. HBO’s portrayal not only engages contemporary audiences with this remarkable historical narrative but also revives interest in the legacies left by these illustrious families and their now-lost residences.
As historians and architects look back on this transformative era, it is clear that the Gilded Age significantly influenced the development of New York City, setting the stage for the high-rise architecture and commercialism that dominate the skyline today. From the towering apartments that replaced the grand mansions to the modern developments reflecting luxury living, the imprint of this opulent past continues to be felt in the city that never sleeps.
