Çankırı, historically known as Gangra (Greek: Γάγγρα), is a city in Turkey, about 140 km (87 mi) northeast of Ankara.

[6] In the writings of the 2nd-century AD Greco-Roman writer Ptolemy, the city is referred to as Germanicopolis (Greek: Γερμανικόπολις).

Under these canons, the sect disowned marriage, disparaged the offices of the church, held conventicles of their own, wore a peculiar dress, denounced riches, and affected special sanctity.

The continuity of the city's name from ancient times across languages is of note: Hangara for the Arabs, Gagra for the Jews and Tzungra or Kângıri or Çankıri for the Turks.

Other locations to the north of the city center feature more humid characteristics (Köppen climate classification: Dfa and Dfb).

Other towns included in the larger industrial area of the city are Şabanözü, Çerkeş, Ilgaz, Kurşunlu, and Yapraklı.
