The Delta Psi, Alpha Chapter fraternity house is located at 434 Riverside Drive in the Morningside Heights neighborhood of Manhattan, New York City. It was purpose built in 1898 and continues to serve the Columbia Chapter of the Fraternity of Delta Psi (aka St. Anthony Hall), a social and literary fraternity. The chapter house was designed by two prominent New York City architects, Henry Hornbostel and George Carnegie Palmer. At this time of its construction, it was "the best appointed and most costly [fraternity] building that has ever been erected in the United States".
