The University of Salamanca was founded in 1134 and given the Royal charter of foundation by King Alfonso IX in 1218. It is the oldest founded university in Spain and the third oldest university in the world in continuous operations. The formal title of 'University' was granted by King Alfonso X in 1254 and recognized by Pope Alexander IV in 1255.
Set of buildings that made up the university are situated around the square known as Patio de Escuelas. In this same square is the home of the Doctors of the Queen (15th century), whose façade is Gothic with Renaissance details and is now the Museum of Salamanca.

The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
