St. Anthony Hall
St. Anthony Hall, better known as St. A's is a national fraternity-like organization that was founded at Columbia in 1847 and has chapters at elite universities around the country. It has the greek letter designation Delta Psi.
At Columbia, St. A's owns a building on Riverside Drive adjacent to Woodbridge, between 116th and 115th street. Though highly secretive, the organization is also known for its formalwear parties, and rumors of cocaine use abound.
Once, St. A's kids threw a glass bottle at a black kid, sparking a protest that lasted about five minutes.
