Longstanding archaeological and historical research finally proved the origin of modern Burgas and its rich cultural heritage. The highly favourable geographical location and natural resources in its territory became a crossroads of ancient civilizations already in the 5th millennium BC. In its modern borders, the northwest of district Izgrev near the Lake Atanasovo, the archaeologists discovered and researched a major prehistoric village, which more than two millennia traded with salt and copper ore to distant shores inside and outside the Black Sea.

  During the antiquity on place of the present district Pobeda, a Thracian port was established under the name Sladki kladenci (transl. - sweet wells, perhaps in the meaning of freshwater/mineral water springs). This important location carried out the trade relations between the Thracian Odris kingdom and the old Greek colonies along the west coastline of the Black sea, evidenced by archaeological finds of amphorae once filled with olive oil and wine.
 

One of the "burgs" can be found today in the locality Poda.

  Several centuries later in the locality Poda situated near the Mandra lake outlet to the sea, a fortress with a port was built to supply the Roman colony Deultum with fine goods from the whole Roman Empire. According to a script from the time of emperor Antoninus Pius around the 155 AD, this settlement was known under the name Burg – Burgos. The seaside fortress survived during the following centuries as more authors and cartographers came to call it in Greek Pirgus and in Italian Poros or Foros. Two other major archaeological sites continue their existence in the vicinity of Burgas - the ancient town of Aque Khalide - Therma and the medieval monastery of St. Anastasia located on island of the same name in the Bay of Burgas.

  During the Ottoman Empire the place was retained as a strategically important stronghold, hidden deep at the bottom of Burgas gulf and traced with good roads connecting it with the country inland.

  In the 18th century, when the Black sea was opened to Europe, Burgas was evaluated as an excellent port with high expectations in the trade sector. This is how the predecessors of modern Burgas outlined its historical course, which made the city into the biggest, most successful port as well as a thriving economical centre in Bulgaria. Priority sectors are tourism, trade, heavy and light manufacturing industry, air, water and land transport. The city is proud not only of its large port but also of the fully modernized international airport, a constant tourist flow and a modern university.
