Trinity Church is directly across the street from the club

Trinity Church possesses some of the finest stained glass in America. The five magnificent scenes in the apse and the rose window are by John LaFarge, who also did several others, along with Tiffany, in the nave and transept. Especially important is his so-called Watson Window over the altar in the north transept. The client for the window was Stephen Van Rensselaer Watson - a founder of Erie Savings Bank, Manufacturers & Traders Trust Company, and Buffalo's street railway system - who lived across the street from Trinity in the commodious Second Empire house that is today the Buffalo Club.

LaFarge required that Watson allow him to exhibit the window, before sending it to Buffalo, at the 1889 Exposition Universale in Paris, where, he hoped, it would establish his international reputation as a m,odern master of glass. Greatly impressed by the beauty and originality of the work, the French government awarded LaFarge the Legion of Honor, the highest honor bestowed upon a foreigner.
