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:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
