Hephaestia was a town of Ancient Greece, now an archeological site on the northern shore of Lemnos. It was named in the honor of Hephaistos, Greek god of metallurgy, whose cult was maintained on the island. It was once the capital of the island (8th to 6th centuries BCE), of which only the ruins remain.
The Greek theater dates from between the late 5th and early 4th century BCE. It underwent reconstruction from 2000 to 2004. The theatre has capacity of 200 people in the main area, and additional 1000 outside.
According to the historian Herodotus, the cities of the island of Lemnos, Hephaestia and Myrina, were inhabited by Pelasgians. These Pelasgians had promised to return the island to the Athenians if on any occasion Athenian ships, pushed by the north winds, managed to arrive in less than nine days from Athens to the island. Many years later, the Athenians under Miltiades the Younger made the crossing in eight days. The Pelasgian inhabitants of Hephaestia left the island but those of Myrina resisted and were besieged until they surrendered, around the year 500 BCE.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
