The tour here with the murals inside is absolutely incredible and a complete must when in Tlaxcala…read more They take you through all of the murals which depict the history of Tlaxcala, the Tlaxcaltecos, and the Spaniards from basically the beginning of their existence until fairly recent times (up to Porfirio Díaz). Our tour guide was exceptionally knowledgeable and it was fascinating learning about Tlaxcala's history with corn and tortillas, the four kings, and Tlaxcala as one of the early sites of Hernán Cortés' conquest. The murals are exquisite and absolutely beautiful. The tour runs hourly and takes about 45 minutes. First tours start at 10am, not sure when they end. Absolute must.
