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 Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
