Monte Castello oppidum, like other Etruscan habitats of the island, controlled the ancient ironworks, was strategically located above a hilltop between Ligurian Sea to the north and the Tyrrhenian Sea to the south. It had a rectangular plan (30 x 60 m), consisting of overlapping blocks of local stone. The settlement, which was excavated in 1977, was inhabited since the first half of the 4th century BC. It was settled until about 250 BC, until the Roman conquest of the island of Elba. Among the recovered archaeological materials, now preserved at the Archaeological Museum of Marciana, there is a valuable terracotta head with a tapestry of Atelier des petites estampilles, the Ferrara T 585 skyphoi, Genucilia type plates, grain-bearing ores, Etruscan amphorae And Greek-Italic, truncopyramidic weights, fusaiole and webbing spools. Noteworthy is the presence of pavement in opus signinum.
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.
