Western gate. One of the two known city gates is on the south and the other is the Western Gate. The monumental structure, which is also the main entrance, is on the west, measures 12 x 24 m, and it is triple arched. It is supported by city walls on each side. On the pediment that rests over the arches, the relief of two kneeling Persians and carrying flags and standard form the focal point of the façade. Nikes carrying garlands are on the pilasters. On the architrave of the exterior surface of the gate, the following is written with bronze letters: [transl.] “To the Emperor Caesar Trajan Hadrian Augustus; grandson of deified Nerva, son of deified Trajan, Pontifex Maximus, tribunus for the 13th time, consul for the 3rd time, father of the land, and to Sabina Augusta …. Colony.” On the interior surface, the following is written: “C. Julius Asper Pansinianus, mayor for the 5th time, major, constructed and ornamented at his expense”. On the frieze over the architrave Hippocampus, Triton, Amazon shield, armour, and various weapons are depicted in relief. The gate was constructed for Hadrian after 120 AD, and after a victory in 200 AD it was rearranged as an arch of triumph.
