The Erechtheion. The temple was built between 421 and 406 BC. Its architect may have been Mnesicles, and it derived its name from a shrine dedicated to the legendary Greek hero Erichthonius. The sculptor and mason of the structure was Phidias, who was employed by Pericles. It was extensively described by the Roman geographer Pausanias, writing a century after it had been restored in the 1st century AD. The internal layout has since been obscured by the temple's later use as a church and possibly as a Turkish harem.
