St. Paul's Chapel on the Morningside Heights campus of Columbia University, is an Epicopal church built in 1903-07 and designed by Howells & Stokes. The chapel has excellent acoustics for concerts, and a small vault in the basement is the location of the Postcrypt Coffeehouse, which "might be the most haunting (not haunted) performance space in the City."
