Pollença’s most emblematic monument is the Castell del Rei, one of the island’s three rock fortresses in the Valley of Ternelles, approximately 492 meters high. In Roman times, it was used as a fortification, and during the Muslim period it was (along with the Castle of Alaró) the last stronghold of resistance from the troops of Jaume I of Aragon, who invaded Mallorca in 1229. They resisted until March 1231.
Another prominent historical fact related to the castle was the resistance offered in 1343, and during a three-month siege, by the last of those faithful to the king of Mallorca Jaume III, after he lost his kingdom and had annexed to the Crown of Aragon.
The castle was used as a watchtower rather than grounds for defence. It was abandoned in the 18th century and is currently in ruins, of private ownership and closed to the public. Currently the road leading to the castle has been reason for controversy. Although it is a public road, the owners have managed to restrict access.
References: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.
