This rectangular church has two naves separated by arches, each with beautiful coffered ceilings. It is located at the entrance of the town and is fondly known as the Peineta del Marquesado. It was built by Francisco Roldán in 1545 and some elements reflect the Cathedral of Guadalix.
The brick tower is at the far right end of the building and is divided into four sections. One of the sections is particularly striking due to its octagonal shape and its glazed ceramic roof. An alfiz, which is an arch typically seen in mosques of the time, frames the main entrance. Inside there is a beautiful triumphal pointed arch, a choir with Mudejar elements and a magnificent altarpiece with three sections. It is a valuable Baroque work of art dating back to the first half of the 18th century with stunning paintings of the Virgin Mary and angels, and fantastic colours, especially green and blue.
