St. Isidore's Collegiate Church

St. Isidore's Collegiate Church is a baroque basilica in Madrid's historic center that once served as the city's cathedral. Two tall towers flank the white stone facade, which features round arches and rectangular windows.

Construction started in 1622 under architect Pedro Sánchez and lasted more than four decades until completion in 1664. In the 19th century the building temporarily took on the role of Madrid's cathedral.

This basilica serves as the burial place of Saint Isidore, Madrid's patron saint, whose mortal remains draw pilgrims and worshippers from across the city. On feast days people gather here to continue the tradition of honoring this farmer saint.

The church stands at 37 Calle Toledo a short walk from Plaza Mayor and opens its main door to visitors during the week. The entrance sits at street level and allows direct access to the nave.

Beneath the main altar lies an old well connected to Saint Isidore's miracle of rescuing his son from the water. The well remains preserved today and forms an unusual part of the church structure.
