The Remezijana – Remesiana archaeological site is located in the nearer urban area of Bela Palanka in East Serbia, on the left bank of the Koritnik River, which borders the eastern side of the settlement and joins the Nisava River in the northeastern part of the settlement. The name of this city was often changed in the earliest period, so it was first time mentioned in the 3rd century as the Remisiana, in the 4th century the settlement was known as Romansiana, while in the 6th century it is called Rumisiana. The city is mentioned in ancient descriptions – travel itineraries in several versions, e.g. in c 3rd and c 4th, in Itinerarium Antonini the name of the city is Remisiana, in Tabulae Peutingeriana – Romesiana, in Itinerarium Burdingalense – Romansiana.
The Roman and the Early-Byzantine stronghold of Remesiana, of the irregular rectangular basis, with polygonal towers, was erected on the trading road between Naissus and Serdica /nowadays Nis and Sofia/. Epigraphic monuments of the Remesiana site testify on the early formation of the settlement which gained the urban status probably during the reign of the Emperor Traian, and also on its significance at the beginning of the 3rd century. Remains of the civil basilica with semicircular apse on the western side and some representative structures in its proximity were discovered within the fortification walls, as well as ruins of the antique structures in several spots. Outside the fortification walls of Remesiana were three-nave basilica with the baptistery, the villa and necropolis along the access roads from the northern, eastern and southern sides of the settlement. Since the 4th century the Remesiana settlement became the seat of the Bishopric, with Bishop Saint Nicetas who lived and worked here. The urban scheme of the late Roman town of Remesiana was not changed in the 6th century, during the intense contruction campaign of Emperor Iustinian.
After the Roman conquest, the Remesiana settlement became part of the Province of the Upper Moesia. Epigraphic finds indicate the early formation of the settlement, which was the significant urban aglomeration with defined administration since the 2nd century, during the rule of Emperor Traian. The settlement was probably the sea and the seat of the administration of mining area, that had extraordinary significance for the Dardania, rich in mines /metalla Dardanorum/. As the important economic branch of that historical period, gold mining greatly contributed to the faster development of the settlement, and as the imperial domain part, the whole area gained urban appearance. The Romanization of the indigenous population greatly influenced the overal cultural frame of the formation of the settlement. The central administration of the Empire conceived the policy of Romanization of some areas, with the aim to ease the exploit of natural resources. This is how the toponym of Daltames appears in the area of Remesiana settlement.
At the beginning of the 2nd century there was the military camp – castrum at the Remesiana settlement. This would also be the first ever devised form of the urban settlement, but its location is still uncertain. The archaeological excavations at the Remesiana site have not designed the remains of the earliest fortification. In many localities, the late Roman and early-Byzantine fortifications were established by enlargement and reinforcement of the first military camps. In that case the walls of the military camp of the Remesiana site would have been located within the basis of the late Roman stronghold. Construction of such strong fortification is possible reason for destruction of the former military camp, as per archaeological excavations that resulted in no identified finds of the military camp.
The economic and cultural significance of the Remesiana settlement in the previous historical period contributed to its status of the sea of the Bishopric at the end of the 4th and the beginning of the 5th century. On this testify the presence of the famous theologian and Bishop of that time – Nicetas /330-410/, the renown missionary and the ecclesiastical writer whose name was denoted with Remesianensis. Some time later, there was another important bishop at the Remesiana – the episcopus Remesianensis Diogenionus. Saint Nicetas from Remesiana was the Bishop of Remesiana. Some ancient texts, including the Order of Catechizing, considered Bishop of Remesiana Nicetas to be one of the fathers of the Church, and both in the Catholic Church and in the Orthodox Church he is considered to be a saint. He was one of the commissioner of the true Orthodox Christianity – the Orthodoxy. »Te Dei« – »To You my Lord« are the work of Saint Nicetas. Years of Nicetas’s life coincide with the period of the final battles against Arianism, which extend to the beginning of the 5th century. Saint Nicetas lived in the second half of the 4th century, surrounded with other bishops (Serdica, Naisus…) who were his opponents Arians, supported by rulers of that time, who were also Arians. Saint Nicetas was supposed to baptize the whole tenacious population of the Bessi Thracian tribe. Saint Nicetas translated the Bible into their language. The Besi tribe is often regarded to have populated the lower course of the Maritza river, but have moved further as the significant gold miners, and they have settled in the areas rich in gold. The archaeological finds of this tribe are small stone mounds with an urn or scattered ashes in the central pit with the whole mound covered with stones. Coins dating from the 4th century were found in those mounds. This was very old way of inhumation for this historical period. Some analogies connected with the Bessi tribe are found in the Rhodope Mountains.This population for long period was resistant to the new lifestyle patterns, and preserved their burial rituals, that confirms their features. It is also mentioned in the old archives that Gots and Sarmatians who were Arians were baptized by Saint Nicetas who converted them into the true faith. During the reign of Saint Nicetas, the Remesiana basilica was turned into the Christian shrine, and another one was built extramuros with the small graveyard.
Sondage excavations at the Remesiana site started in 1956, and in regard with the building works carried out in the town, with some interruptions they last until the present. The conservation works are completed on excavated finds of the Remesiana site.
