The Spanish Governor's Palace is a National Historic Landmark in the city of San Antonio, Texas. Built in the first half of the eighteenth century, it was originally intended to protect the nearby San Antonio de Valero Mission (the Alamo) and the growing colony. It is considered the sole remaining example of an aristocratic early Spanish house in Texas. The National Geographic Society has called the landmark "the most beautiful building in San Antonio."
The building is currently maintained by the City of San Antonio and is open to the public as a museum.
The palace is located in between Market Square and the San Antonio River Walk near the current city hall. The address is 105 Military Plaza.
