Opposite Lyssiktratous street of Vasilissis Amalias Avenue you will see the tall columns of the temple of Olympian Zeus, which was the city's largest sanctuary.

According to the myth it was founded by Deucalion. Work stared on the temple in the early 6th BC. Then under the Peisistratids four architects - Antistates, Kalescros, Antimachides, and Porinos- began to build a new temple, a project that was revived in 175BC with the help of Antiochos IV whose death put a stop to construction.

This enormous temple was finally completed during the reign of Hadrian, who inaugurated it in 132 AD
It had 104 Corinthian columns, a length of 110.5m and width of 43.7om. Between 253 and 260AD its destruction began and by the 15th c only 21 columns were still standing given that the Turks were fond of crushing them to make them look white-washed.
Today 16 columns are erect, one fallen, to remind us of its former grandeur.
