Among the best surviving works of McKim, Mead & White, New York's leading turn-of-the-20th-century architects (and members of the club), this 1899 pink Milford granite palace was built for an exclusive club of degree-holding men. Note the crests of various prestigious universities engraved into the facade above its windows. The club's popularity declined as individual universities built their own clubs and as gentlemen's clubs became less important to the New York social scene. Still, the nine-story Italian High Renaissance Revival building (the facade looks as though it's three stories) is still known for its exclusive membership (male and female), declaring itself "New York's premier social club." The building's interior is a bounty of marble, gilded columns, and murals, but the club is private so you'll have to make do with its grand exterior.
