The Necropolis of Mesu 'e Montes complex consists of 18 domus de Janas (type of pre-Nuragic chamber tombs in Sardinia). The site dates from the Neolithic to Middle Bronze Age. Of particular note, tombs I and II with 12 chambers each, decorated with a variety of features, a ceiling reproducing a gabled roof and a circular hearth sculpted into the floor; and tombs III, IV and XVI, all of architectural interest, with a curved stele in the centre of the exedra.
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.
