A sanctuary with three fana (Gallo-Roman temples), a small bath building, an amphitheatre, several necropolis and remains of buildings where discovered in 1763 and excavated in 1956 near Bern.
It has an ellipsis shape arena, whose axis are 28 x 26 metres, two walls which could be an entry at one end, and a niche at the other end. Its blenches were probably wooden made. Long regarded as an amphitheatre (it would one of the smallest in the Roman empire), the building could be also a Gallo-Roman theatre (according a recent hypothesis), and the walls opposite to the niche would be the basis of a wooden scenic building. The proximity of the amphitheatre with the sanctuary is significant and it could used for various public shows as well as religious ceremonies.
At the north of the amphitheatre, in the forrest, a small public bath-house is visible under a modern roof. The building, discovered in 1847 and entirely excavated between 1937 and 1938, was 20 metres long and 12 metres large. The bath-house has a cloakroom (apodyterium), a cold bath (frigidarium) with a pool, a warm room (tepidarium) and a hot bath (caldarium). The underfloor heating system is quite well preserved.
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.
