The walled medieval town of Cabrejas del Pinar was the leader of its Community of Burgs and Land and there are some traces left of the walled enclosure and fortress that protected the locals. The castle was built in stone on top of a high rock possibly between the 13th and 14th century.
Some of the walls, doors and the keep are still visible which helps understand how the fortress’ layout once was. The quadrangular keep was built in stone masonry and reinforced with ashlar on the corners. On some of the higher floors, you can still see wood fixed in holes that supported the wooden floors on each of the four stories. The access door can still be seen and is located on the south-east wall defended by watchtowers and an opening.
On the eastern part of the walled enclosure, there is still a circular watchtower placed there possibly in the 10th century in order to have better visual control over the Caliphate’s territories.

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.
