The city of Burgas has a population of almost 200,000 people according to recent data, and is the second largest city at the Bulgarian Black Sea coast. It is also the fourth largest city in the country, following Sofia, Plovdiv and connecting Varna. It is situated in the farthest western part of the Burgas Bay and 390km east of Sofia. Due to the low level of the coast in the area, three lagoon-lakes (the Atanassovo, Burgas , and Mandren lakes) lie in the area surrounding the city.
