The gate is located at the beginning of Curetes Street. It is a two-storeyed edifice. In the lower storey there is a wide arched passageway, and in the upper storey there are six columns in a row. Another span like this one stands just to the left, and an arch would have connected the two. The gate was originally built in 117 AD, then rebuilt after an earthquake in 270 AD. The gate was partially restored in the late 1980's.
Hadrian's Gate had a center passage spanned by a missing arch while the flanking side entrances are capped by architraves that survive. The second story was formed of four pillars and the third story of six pillars no longer exist.
