Ruins in Burgas
Located at the end of the village, the remains of antique town Deultum and the medieval Develt, give the name of the contemporary village of Debelt (it is a modification of the name Deultum). The Roman Colony of Deultum was established here in the beginning of the 70s of the 1st century, during the ruling of emperor Tit Flavius Vespasian, by the veterans of the 8th Augustan Legion. This is the only colony of free roman citizens on the present Bulgarian territory. There was a port by the town, which was situated by the present Mandrensko Lake.
Thracian tomb Kuhata mogila is located 100 meters from the road to Pomorie and is dated II-III century. It is a combination of typical Thracian tomb and Roman mausoleum. The height is 8 meters and has a diameter of 60 meters. It is open for visits and tours.
