This colossal temple is the largest in Greece and it took over 700 years to complete. Originally it had 104 Corinthian columns that reach 17 meters high, of which only 15 remain. The credit for its completion goes to Adriano who placed a giant gold and ivory statue of Zeus inside. The Arch of Hadrian, that functioned as a gate to the enclosure, connects to the road that passes by the Lysicrates monument and also passes along the way of Tripods. It is here that the winners of the ancient theater competitions dedicated their trophies to Dionysus. The Marble Arch served as a border between the old city and the Roman city.
