Knights of Columbus Building (New Haven, Connecticut)
The Knights' Tower serves as the international headquarters for the Knights of Columbus and is home to the Supreme Council. Led by the Supreme Knight, the Chief Executive Officer of the Knights, the building provides administrative support and leadership for more than 15,000 councils worldwide. The cylindrical towers at the corners give the structure a simple geometric form and represent the four core principles of the Order: Charity, Unity, Fraternity, and Patriotism.
