The location of the gate is in walking distance of Syntagma Square, which makes it a central place in the modern city of Athens. In Roman Greece, it was built on the ancient road that connects between the ancient city center, with the Ancient Agora of the Acropolis, and the Olympieion, and the south-east side of the city.
It is interesting that the gate was not a part of a wall around the city, but a gate and arch on its own, along the road. During the Turkish Ottoman rule in the 18th century, the Turks combined the gate with a protective wall for self-protection that they built, against a possible Albanian invasion.
At the top of the arch, Corinthian columns were added to the sides of the walls.
The writings show that the arch was built it seems on the dividing line of Ancient Athens, to the west of the new city of Hadrianoupolis, and on the East side, Theseus.
Some see these carvings as a sort of declaration, of Hadrian, as the hero of the new Athens, and the one who replaced Theseus.
