Kavala is a city in northern Greece, the principal seaport of eastern Macedonia and the capital of Kavala regional unit. It is situated on the Bay of Kavala, across from the island of Thasos. Kavala is located on the Egnatia motorway and is 160 km from Thessaloniki.

The city was founded at about the end of the 7th century BC by settlers from Thassos, who called it Neapolis. It was one of the colonies that the Thassians founded along the coastline in order to take advantage of the rich gold and silver mines of the territory, especially those located in the nearby Pangaion mountain.

Kavala hosts a wide array of cultural events, which mostly take place during the summer months. The top festival is the Festival of Philippi, which lasts from July to September and includes theatrical performances and music concerts. Since 1957, it has been the city's most important cultural event and one of the most important of Greece. Cosmopolis is an International Festival held in the Old Town of Kavala that offers an acquaintance with cultures around the world through dancing and musical groups, traditional national cuisines, cinema, and exhibits at the kiosks of the participant countries.

Fish and sea food, as well as the products of the local livestock breeding and agricultural sectors are the prevailing elements of Kavala courses. In Kavala, the traditional local recipes have been influenced by the cuisine of the refugees from Pontos, Asia Minor and Kappadokia.
