The Middletown chapter of the Alpha Delta Phi literary society, based at Wesleyan University, was formed in 1856. The fraternity’s first chapter house was built in 1884. It was demolished twenty years later and replaced on the same lot (185 High Street) by the current building (completed in 1906) designed by Charles Alonzo Rich (who also designed two dozen buildings at Dartmouth College between 1893 and 1914). An addition was built onto the rear in 1925. Alpha Delta Phi has been coed since 1972 and is one of the coed chapters that withdrew from the fraternity to form the separate Alpha Delta Phi Society in 1992.
