Back in the 1980s, when I visited West Point Military Academy on the Hudson River in New York, I was surprised to find out that one of the stained-glass windows in the West Point chapel, was of a Knight of Malta. There were various Knights and soldiers represented in the side windows, and next to a Knight of the Holy Sepulchre, was a fully armored Knight of Malta, holding a sword in one hand and a cross in the other. He also has the Maltese cross imprinted on his chest.
Below the image it was mentioned that the window was probably paid for by the Munificent Benefactors of the Knights of Malta, an organization that is still going strong. They do a lot of fund-raising all around the world, and especially in the New York area.
