Orizaba’s wonderful Museo de Arte del Estado is housed in a gorgeously restored colonial building dating from 1776 and attached to the side of a church. The museum is divided into rooms that include Mexico’s second-most-important permanent Diego Rivera collection, with 33 of his original works. There are also contemporary works by regional artists. Guides give complimentary tours in Spanish. The museum is 2km east of Parque Castillo.
