During the time of emperor Vespasianus  (69-79  AD) over the north shore of the river Sredetska, a colony of  military veterans from the Eighth Augustan Legion, was found over the old Thracian settlement Deultum.  The name of the new city was  Colonia Flavia Pacis Deultensium. Those legionaries became famous during the putting down of the great rebellion in Judas and during the civil war demonstrating of the new emperor’s authority.  Under Roman law, the veterans were given a large territory between the lakes Burgas and Mandra. It is interesting that the name of the ancient city Deultum has Thracian origin and means "a place between two marshes," which refers to the terrain features of this area in the past and even today.
The biggest prosperity of Deultum begins during the Severan dynasty (at the end of the 2nd - beginning of the 3rd century). Back then the city covered a territory of more than 250 decares (250 000 sq.m), it had a well developed infrastructure, which was set according to the cardinal directions. Temples of Asclepius and Cybele were erected in its central part of the city. Furthermore local gods like the Thracian Horseman and Heracles were praised. During the time of Emperor Septimius Severus, a temple of the emperor’s cult was also built here. For fifty years the city coinage emissions of bronze coins. The images on both sides of the coins give us important information on how the city looked like, its building, religious life and economy.

Archaeological research have been conducted in Deultum for over 32 years. Revealed is part of the ancient city, founded in 69 AD by the Roman Emperor Vespasianus  as a colony of Roman soldiers from Legio octava Augusta (Eighth Augustan Legion). In the Middle Age Debelt acted as a border between the Bulgarian kingdom and Byzantium and played an important role in border relations between the two countries. In the beginning. of the 9th century to the north of the city was built the Old Bulgarian border ridge Erkesia.
