Temple of Hephaestus - Athens, Greece
On top of Agoraios Kolonos hill, which is delimiting the Ancient Agora of Athens to the west, stands the temple of Hephaestus, broadly known as "Thisio". It is one of the best preserved ancient temples, partly because it was transformed into a Christian church. According to the traveller and geographer Pausanias (1, 14, 5-6), two deities were jointly worshipped in the temple: god Hephaestus, protector of all metallurgists, and goddess Athena Ergani, protecting all potters and the cottage industries.
The identification of this temple as "Hephaesteion" (location of worship of the god Hephaestus) was ascertained by the excavations and investigations that brought to light metallurgy workshops on the wider area of the hill, thus outshining earlier opinions presuming that Theseus, Hercules or Aris (Mars) were the deities worshipped there. The temple was probably erected between 460 and 420 BC by a yet unknown architect, to whom, however, are attributed other temples of similar structure in the Attica region.
