One of the most famous attractions in the city of Kavala is the Aqueduct, which locals call the Kamares (Greek means "arch"). Magnificent old structure connects the old and new parts of the city. The aqueduct is a three-tiered arched structure (level of the city, the water level and the level of birds) with a length of 280 m and height 25 m. To the present day survived about 60 arches of four different sizes.

Is aqueduct in the Eastern part of downtown on the square Nicotera and in the immediate vicinity of the area of Panagia (old town), old market and the old city docks. Thanks to the aqueduct, the city was constantly drinking water which flowed down from the mountain springs of Panga.

Despite the fact that the aqueduct itself has a "Roman origin", the structure that we see today dates from the 16th century. Built aqueduct on the orders of Suleiman the Magnificent on the old ruins of Byzantine walls from the early 14th century. These ancient walls were built by Andronikos II Palaeologus as the city defense system against the Catalans. In the wall was also hidden the aqueduct that supplies the city with water from the source. In the early 15th century, the town was attacked, and the supply was destroyed. This is one of the few examples of Byzantine aqueducts, as the Byzantines themselves used the wells and special tanks for water storage. During the rule of the Ottoman Empire the remains of Byzantine buildings were replaced with real arched aqueduct (1530-1536).

Kamares aqueduct was used to supply the town with water up to early 20th century. In 1997, restoration works were carried out this monumental constructions. Today the old building is a landmark of the city.
