Monastery of San Isidoro del Campo

It was built in 1301 by Alonso Pérez de Guzmán. It was the result of a concession from Ferdinand IV of Castile in 1298 and the purpose was for the remains of Alonso to rest there. It has several works of art of some importance by Juan Martínez Montañés. Montañés made a lavish altarpiece. In addition, in the Cloister of the Evangelists there are four interesting 15th century wall paintings. There are also other notable pieces, such as a Christ by Pedro Roldán, 17th-century stained glass, relics and remains of Saint Eutiquio,. The monastery housed one of the best libraries in Spain.
