Querétaro's art museum, located adjacent to the Templo de San Agustín, occupies a splendid baroque monastery built between 1731 and 1748. It's worth visiting to see the building alone: angels, gargoyles, statues and other ornamental details abound, particularly around the stunning courtyard.
The ground-floor display of 16th- and 17th-century European paintings traces influences from Flemish to Spanish to Mexican art. Here, too, you'll find 19th- and 20th-century Mexican paintings. The top floor has works from 16th-century Mannerism to 18th-century baroque.
The museum has a good bookstore-cum-gift shop.
