The Church de San Andrés is located on the site of a former church from the times of Moorish occupation. The former church had been frequented as a parish church by the patron saint of Madrid, San Isidro Labrador, and his wife Santa María de la Cabeza, who lived nearby.
The adjacent chapel of San Isidro was built at the site of the saint's house. Its construction began in 1657, after the saint was canonized in 1622. Further reconstructions were performed in 1663 and 1669, and later in 1783 and 1789. The initial construction in Baroque style was fashioned by José de Villarreal, and later Pedro de la Torre and Juan de Lobera. Much of the internal decoration, including paintings, were destroyed during the Spanish Civil War.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
