Casa de Cortés, Veracruz
One of Mexico’s (and possibly north America’s) oldest remaining colonial buildings is the Casa de Cortés in Veracruz. Due to its convenient port location, Veracruz state as a whole is full of colonial architecture; however, La Antigua’s Casa de Cortés — allegedly constructed between 1520-23 — is one of the most historically significant. While it is now in major disrepair, given the ceiba trees that have grown underneath and through the walls, it’s still an unmissable and important building.
