St Mary the Virgin Church is built in Perpendicular Gothic (late 15 C) and has a 13 C Decorated Gothic tower. From the tower, admire the view of the city's dreaming spires, domes, quads, and the surrounding hills. It has a charming and unusual Baroque porch by Nicholas Stone (1637). St Mary's is the University Church, and adjoins the first rooms used by the university, Congregation House, with the first library just above.
