Nearby is the monumental Gate of Domitian, constructed around 83 AD to serve as the northern entrance to the city. It has three arches and two towers, and originally had two stories. The gate led into a colonnaded street known as Frontinus Street (named for its builder, the proconsul of Asia, who also built the Gate of Domitian). This was the heart of the city during Roman times, containing shops and public buildings under covered walkways.
To the north of the main ruins and along the modern road is the north necropolis (graveyard), the largest in Anatolia. It contains more than 1,200 tombs of various types, including tumuli, sarcophagi and house-shaped tombs from the Hellenistic, Roman and early Christian periods. Some have Jewish inscriptions.
