Neighbouring provinces are Uşak to the north, Burdur, Isparta, Afyon to the east, Aydın, Manisa to the west and Muğla to the south.

The province has strong biblical connections: in the Book of Revelation, John the Evangelist hears a loud voice which sounded like a trumpet when he was on the island of Patmos.

The voice says: "Write down what you see and send the book to the Churches in these seven cities: Ephesus, Smyrna, Pergamum, Thyatira, Sardis, Philadelphia and Laodicea".

The Church of Laodicea was a sacred place even in pre-Christian times, and is still visited by Christians today, although it lost its importance to a great extent during Byzantine rule.

Turks were first seen in Denizli in 1070 when Afşin Bey, under the control of the Seljuk Sultan Alp Arslan, raided the area.

After World War I, when the Greek Army captured the city of İzmir on May 15, 1919, one of the first centres of Turkish resistance formed at an open-air meeting in Denizli.

In appearance the Denizli cock has black eyes, dark grey legs, a long neck, and a red crown.
