The Monastery of El Escorial was built by King Philip II in the 16th century to commemorate a military victory and serve as a royal pantheon for the Habsburg dynasty. Designed by architects Juan Bautista de Toledo and Juan de Herrera, it is characterized by its sober, Renaissance style. Today it is a UNESCO World Heritage Site.
