Location: The temple is located in the area of Thiseion and is built on the hill of Agoraion Kolonos. It is accessible from the public and is part of the archaeological site of the Ancient Agora.

One of the best preserved ancient temples is the Temple of Hephaestus, built in 450 BC during the Golden Age. The temple was originally built as a dedication to the god Hephaestus. It is also noteworthy that work on the temple began in parallel with that on the Parthenon and the Temple of Poseidon at Sounion. Around the 7th century, the ancient temple was converted into a Christian temple. In 1833, the temple was the site of the celebration of Otto's arrival in Greece. From then until 1934 it was used as a museum, until it was converted back into an ancient monument and serves like a one till today..
