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:Goryōkaku (五稜郭) (literally, 'five-point fort') is a star fort in the Japanese city of Hakodate on the island of Hokkaido. The fortress was completed in 1866. It was the main fortress of the short-lived Republic of Ezo.
Goryōkaku was designed in 1855 by Takeda Ayasaburō and Jules Brunet. Their plans was based on the work of the French architect Vauban. The fortress was completed in 1866, two years before the collapse of the Tokugawa Shogunate. It is shaped like a five-pointed star. This allowed for greater numbers of gun emplacements on its walls than a traditional Japanese fortress, and reduced the number of blind spots where a cannon could not fire.
The fort was built by the Tokugawa shogunate to protect the Tsugaru Strait against a possible invasion by the Meiji government.
Goryōkaku is famous as the site of the last battle of the Boshin War.
