St. Paul's Chapel is the chapel of Columbia University in New York City. Designed and built from 1904 to 1907 by I. N. Phelps Stokes of the architectural firm Howells & Stokes in an elaborate mixture of Italian Renaissance, Byzantine, and Gothic styles, its interior features Guastavino tile vaulting in intricate patterns of aged red brick. Three stained glass windows by John La Farge adorn the apse. St. Paul's Aeolian-Skinner pipe organ is renowned for its fine tone. The chapel contains an Altar for Peace by George Nakashima, a wooden table with natural edges in his signature style. St. Paul's is referred to as "Columbia's most spectacular building" in the Eyewitness Guide to New York and is a New York City Landmark.
The chapel was the first building on Columbia's Morningside Heights campus that was not designed by McKim, Mead, and White.
Many religious groups use the chapel throughout the week for their meetings. Several non-religious student groups also use the chapel. The most notable of these are the student magazine The Blue and White and the Postcrypt Coffeehouse, a folk music venue featuring live music weekly. The basement of the chapel houses the Postcrypt Art Gallery. At commencement, the university uses St. Paul's for a Baccalaureate Service to commemorate graduates' achievements. The chapel is also popular for weddings.
