The Monastery of San Pedro de Villanueva is a Romanesque monastery previously owned by the order of Benedictines. A church here supposedly was founded by Alfonso I the Catholic, son in law of Pelagius of Asturias. The remaining structures now date from later periods. In the 12th century, the monastery was built adjacent to the church. The buildings underwent substantial rebuilding after the 17th century. In 1835, the monastery was dissolved. In the present century, the monastery has become a national hotel, a Parador. The church is still in use.

The Clementinum is a historic complex of buildings in Prague. 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.
