The goddess who was worshipped most in Ephesus was Artemis; her temple, the temple of Artemis (Artemision) was built around the 6th century BC and, being 425 feet long, was considered to be the largest building of the ancient world and was one of the Seven World Wonders. The temple of Artemis was burned down by Herostratus at 356 BC in order to immortalize his name, but was rebuild later on. Most parts of this temple are now housed at the British Museum of London.
Another main attraction of Ephesus is the Curetes Street, that took the name of the “Curetes”, who were 9 high officials of Artemis. The curetes street is stretching between the Hercules Gate and the Ancient Library of Celsus that was built in Roman times (around 135 AD).
