Situated 250km (155 miles) northwest of Mexico City, it is here that the Emperor Maximilian was captured, tried and executed, and where the present Mexican constitution was drawn up in 1917. A former San Franciscan monastery is now a local museum, whilst the San Agustin monastery has become the Federal Palace. The mansion of the Marquis Villa del Aguila, who ordered the building of the town’s aqueduct, can be found in the Plaza de la Independencia. The town has excellent hotels and restaurants.
