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.

Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
