This building, originally a Quonset hut purchased from the military after World War II, contains four art studios for art classes. The building is named after the Convent of San Marco in Florence, Italy, where the Dominican Fra Angelico painted his famous frescoes in the 15th century.
As the building is named after an artistic location, it is fitting that beautiful works of art are routinely created here. San Macro is heavily used for ceramics, watercolor, painting, and sculpting classes. Much of the art done by Dominican students is created and completed in San Marco and later put on display in the San Macro Gallery located in Archbishop Alemany Library.
