Tlaxcala is the small capital of Mexico's smallest state, an hour north of Puebla and close enough to Mexico City for a long day trip. It is not grand in the way Puebla is grand. Its appeal is more compact: painted colonial buildings around the main plaza, a 16th-century Franciscan complex, bright churches, and a historical memory that still circles around the Tlaxcalans' alliance with the Spanish against the Aztec Empire.
The centre is easy to walk. Plaza de la Constitución is framed by arcades and government buildings, while the Palacio de Gobierno holds murals by Desiderio Hernández Xochitiotzin that tell Tlaxcala's history with real force. A short walk uphill brings you to the former Franciscan monastery and cathedral, one of the oldest church complexes in Mexico.
Tlaxcala also has a good food identity for its size. Look for pulque, mole, escamoles in season, and regional antojitos rather than generic tourist fare. It is a worthwhile stop if you want colonial Mexico with fewer tour buses and a sharper local story.
