Born from Estudios de la Villa (1346), Colegio Imperial (1603), and Reales Estudios de San Isidro (1625) San Isidro Institute is the oldest school in Madrid and possibly in Spain.

Located in the heart of Madrid, in the La Latina district, the building contains treasures such as a magnificent baroque cloister (1672), a Baroque staircase and an elegant chapel (1723), among other ancient works of art. On the staircase we find this lovely little museum dedicated to the history of the school, with exhibits on the ground floor, which explain its origins and curriculum, and maps, photographs, and other objects on the upper floor. It also has a recreation of an old classroom. Free entry
