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 Roman Theatre of Mérida is a construction promoted by the consul Vipsanius Agrippa in the Roman city of Emerita Augusta, capital of Lusitania (current Mérida). It was constructed in the years 16 to 15 BCE. One of the most famous and visited landmarks in Spain, the Roman Theatre of Mérida is regarded as a Spanish cultural icon and was chosen as one of the 12 Treasures of Spain.
The theatre has undergone several renovations, notably at the end of the 1st century or early 2nd century CE (possibly during the reign of Emperor Trajan), when the current facade of the scaenae frons was erected, and another in the time of Constantine I (between 330 and 340), which introduced new decorative-architectural elements and a walkway around the monument. Following the theatre"s abandonment in Late Antiquity, it was slowly covered with earth, with only the upper tiers of seats (summa cavea) remaining visible.
