The church Izydora (San Isidro) is located in the historic center of Madrid. It contains the remains of Saint Isidore, patron of the city and his wife, Saint Maria de la Cabez. This temple is one of the most representative buildings of the religious architecture of Madrid from the 17th century. Inside you can admire the sarcophagus with the relics of St. Izydor, the altar by Sebastian Herrera Barnuevo, considered the artist's greatest masterpiece and several paintings by Francisco Rizi.
The temple was designed in 1620 by architect Pedro Sánchez. It was modeled on the famous Roman church Il Gesu. The Church of San Isidro was part of the Colegio Imprerial de Madrid school, which was run by the Society of Jesus (Jesuits). In its heyday, this institution competed with the best Spanish universities. In 1767 it changed its name to Colegiata de San Isidro. It is currently a public institution.
