Santa Cruz de Cangas de Onís is a small Roman Catholic chapel in Cangas de Onís, the first capital of the Kingdom of Asturias. It was founded on an artificial mound (a pagan dolmen) by Favila, second king of Asturias, and his queen, Froiliuba. It was begun in 737 and consecrated that same year on 27 October according to its original foundation stone, which has been called the first literary monument of the Reconquista.
Santa Cruz originally housed the Cruz de la Victoria, an oak cross supposedly carried by Pelagius, Favila's father, at the Battle of Covadonga. It was probably the first church constructed after the Islamic invasion of Spain in 711.
The church was completely rebuilt on two occasions. First in 1632 and again after its destruction in the Spanish Civil War (1936). Then, local authorities decided to uncover the dolmen beneath it, which had been obscured by a church since the fourth century, when the first chapel was put up on that site. Of the original building only the foundation stone survives.
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).
