The ancient temple of Kavirio on Lemnos is situated 3 kilometers from the archaeological site of Ifestia, just opposite to Tigani Bay. It is an ancient sanctuary dedicated to the two gods Kaviri, mythical gods of northern Aegean with mystic ceremonies.
The sanctuary of Kavirio, which was assumed to have been built around the 6th or 7th century BC, is older than the one in Samothraki, where this particular god was also worshiped. There is also a belief that Kaviri were sons of god Hephaestus. They were thought to be talented technicians and they were worshiped as gods of the sea, the vineyards, and fertility. Kaviria Mysteries were celebrated every year and they were associated with the revival of nature.
The site of Kavirio was brought to light in 1937. The excavations can be seen separated by a trench. There was a telestirio or else initiation hall, a palace and an arcade on one side. On the other side, there is a larger telestirio with twelve Doric columns. The sanctuary contained many inscriptions that gave information about its construction and the history of the island.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
