Burgas (sometimes written Burghaz, Bourgas or Borgas, and, in the middle ages, Pyrgos), a seaport, and capital of the department of Burgas, in Bulgaria (Eastern Rumelia), on the gulf of Burgas, an inlet of the Black Sea, in 42° 27′ N. and 27° 35′ E. Pop. (1906) 12,846. Burgas is built on a low foreland, between the lagoons of Ludzha, on the north, and Kara-Yunus, on the west; it faces towards the open sea on the east, and towards its own harbour on the south. The principal approach is a broad isthmus on the north-west, along which runs the railway to Philippopolis and Adrianople. Despite its small population and the rivalry of Varna and the Turkish port of Dedeagatch, Burgas has a considerable transit trade. Its fine harbour, formally opened in 1904, has an average depth of five fathoms; large vessels can load at the quays, and the outer waters of the gulf are well lit by lighthouses on the islets of Hagios Anastasios and Megalo-Nisi. In 1904, the port accommodated over 1400 ships, of about 700,000 tons. These included upwards of 800 Bulgarian and Turkish sailing-vessels, engaged in the coasting trade.
Fuel, machinery and miscellaneous goods are imported, chiefly from Austria-Hungary, Belgium, Germany and the United Kingdom; the exports include grain, wool, tallow, cheese, butter, attar of roses, etc. Pottery and pipes are manufactured from clay obtained in the neighbourhood.
