Old St. Mary's Cathedral located at Grant Avenue and California Street is the first cathedral built in California. Just a block and a half from the Chinatown Gate, Old St. Mary's also hosts a popular series of lunchtime classical chamber music concerts Tuesdays and Thursdays.
Old St. Mary's was designed by architects William Craine and Thomas England, who followed the instructions of the church's Bishop, Joseph Sadoc Alemany. The Cathedral was erected in 1854 and offered the first English-language school for the Chinese community.
