The Amazing Roslyn Estate of a 1906 Vanderbilt Cup Race Spectator

Clarence Mackay (1874-1938) was the heir to the Comstock silver fortune and was a major figure in the development of the international telegraph business. Before and after the Vanderbilt Cup Races, Mackay would host huge parties for his friends and business associates at his 648-acre estate overlooking the village of Roslyn.

Following the conclusion of the 1906 Vanderbilt Cup Race, William K. Vanderbilt Jr. was asked to address his friends and race officials at the Westbury grandstand. Clarence Mackay was standing to Willie K's left.

The Harbor Hill Estate

Mackay's Harbor Hill estate was one of the largest on Long Island with formal gardens and terraces surrounding the main house designed by Stanford White. This previously published 1920 aerial captured the gardens nearing completion.

The Mackay Horse Statues

Mackay commissioned two 25-ton, 40- foot replicas of the famous Champs-Elysees Marley Horse statues for the west garden. Amazingly, the workers were just ready to hoist one of the horses and the groomsmen on to their pedestals. In 2009, the south statue was still in its place on Harbor Hill in East Hills. The statue is currently being restored by the Roslyn Landmark Society assisted by a grant from the Gerry Charitable Trust. Next week, you can relive the days of the Vanderbilt Cup Races and see the Alco Black Beast roar at this special Roslyn Landmark Society event.

From Robert R:

“Wow, what an estate!

Just sent it to my wife and her sister, who grew up on Morgan’s Island.”
