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.

Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
