Torretrencada is a Talayotic settlement (1000-700 BCE) that was occupied until the Roman conquest in 123 BCE. Several of its monuments can still be seen. They include the talayot a seriest of artificial burial caves dug out of the rocky ground and burial chambers carved in the rock, probably dating from the high medieval period. The taula is one of the most beautiful on the island, with a reinforcement pillar at the back, but all that is left of the surrounding wall is a section underneath the modern dry-stone wall. The site dates back to the post-Talayotic period (650-123 BCE) and was used by the community for performing rituals.
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.
