Castillo Almodóvar, Spain

Castillo Almodóvar, located in the province of Córdoba, served as the setting of House Tyrell, Highgarden. The castle didn’t actually have its debut until the seventh season, however, when Jaime Lannister invaded the Tyrells’ home. In real life, the Roman fortress dates back to the eighth century. Today, the castle hosts all sorts of activities and tours, including an interactive Game of Thrones tour.
