The Rafal Rubí navetas are two tombs of the same type as the Naveta des Tudons, but these are smaller and are unusual in that they are very close to one another. They are group burials with a perforated stone slab at the entrance to the inner chamber, which is split into two levels.
Of the two navetas, the east one is in better condition, as the front was restored in the late 1960s, when an archaeological dig was also carried out during which burial goods were found, including pottery items, rhomboid-shaped bronze pendants and part of a torc. The west naveta was excavated in 1977 and the human remains found in the upper chamber were dated to 904 B.C.The items found are on display in the Museum of Menorca.
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.
