Collegiate Church of San Isidro

The Basilica of San Miguel, built between 1739 and 1745 by the architect Santiago Bonavía, is one of the most beautiful Spanish Baroque churches in the city. The church of Saints Justo and Pastor was there before, dating from before the 13th century, but damaged by a fire in 1690, it was finally destroyed.

The Arzobispal Castrense church was designed by the architect Juan Gómez Mora in the year 1615. The construction of the church began in 1671, half a century after the convent was founded; 73 years was spent in its construction, ending in 1744. The church is now commonly referred to as the Armed Forces Army Cathedral.

The Cathedral of the Armed Forces is the cathedral of the Military Ordinariate in Spain. The church was originally part of the former Bernardine monastery of Madrid, founded in 1615 by Cristóbal de Sandoval y Rojas, Duke of Uceda. The church was designed in the shape of a Latin cross by the architect Juan Gómez de Mora in 1615, but construction began in 1671, half a century after the foundation of the monastery, due to the misfortune of the favourite, and was not completed until 1744. The convent was demolished in 1972. The church was therefore purchased by the Spanish Ministry of Defence around 1980 to house the Military Ordinariate in Spain.
