Hadrian's Gate is one of the main (and the most dramatic) entrance gates into the Kaleiçi district. Considerable stretches of the Hellenistic and Roman town walls on the eastern side of the old town have been preserved, and Hadrian's Gate is the most notable of these sections.

 Erected in honor of the AD 130 visit by Emperor Hadrian himself, this imposing three-arched marble gateway, flanked by imposing towers, is decorated with rich sculptural decorations. As you walk through the arches, look up at the ceiling to view the best preserved carvings.
