Tucked away from Calle Mayor, this is Madrid’s oldest surviving church. The most striking feature is the restored 12th-century Mudéjar (a Moorish architectural style) bell tower. Much of what remains dates in part from the 15th century. The vaulting is late Gothic while the fine coffered ceiling dates from about the same period. Opening hours can be unreliable.
Despite plateresque and baroque touches, much of the interior is a study in simplicity. The architect Juan de Herrera, one of the great architects of Renaissance Spain, was buried in the crypt in 1597.
