Arch of Hadrian Athens. Northwest of the Acropolis, near Plaka and close to Amalias Road, is Arch of Hadrian Athens. The Hadrian Gate or Arch stands on the same site as the temple of Zeus Olympius. Hadrian also built a new neighbourhood. On the border between the old and the new city he build the Hadrian Gate, which is 18 meters high. The gate of Hadrian is identical on both sides except for the inscriptions in Greek letters. In the direction of the Acropolis, it says: "This is Athens, the ancient city of Theseus." On the other hand, in the direction of the Temple of Zeus Olympius, it says: "This is the city of Hadrian, not of Theseus".
