One of the A Coruña's most interesting monuments, San Anton castle (Castillo de San Antón) in A Coruña was constructed during the 16th and 17th centuries. A fortress built on a small island in the bay to defend the city against attacks coming from the sea, it effectively defended the entrance to the city against the English assault led by Francis Drake in 1589. There are some lovely collections of Celtic jewellery that were found on archaeological digs in Galicia on display inside the castle today.
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.
