The Archeological Department was formed by the establishment of the Museum itself. It featured few exhibits until the 1970s of the 20TH century when more extensive research was began in our region. However, until the end of the 20th century, in this department were held only objects found on medieval Trgovište site and the prehistoric tumuli on Pešteri. Materials from other sites are held and today are holding, in institutions carrying out the projects; what with the fact that the Museum employed only one archeologist until 2006, presents the reason why archeological material has not been divided into collections but it is presented as a single assemblage.

In the 1950s, the Museum acquired a hoard of 692 Serbian medieval coins dated from the 13th century, found by chance in the village Postenje. About the same time, several flintstone and stone tools were in the book of entrance of museums material. They represent accidental finds encountered in the broader area of Novi Pazar and the oldest pieces of the Museum.

Naprelje is 3 km to the northeast of Novi Pazar. During the surveying of the route of the railway Raška-Novi Pazar, in 1952 the remains of the site a settlement were found explored to some extent. The site lies on the lower terrace of a slope falling steeply to the field where the riverbed of the river Raška used to be. The settlement was established during the younger Stone Age, the Neolithic, and belongs to Vinca culture. Vinca cultural group belongs to the wider cultural complex of the Neolithic widely spread on the Balkans and in the western part of Anatolia. The finds of ceramics and fragmented figurines from Naprelja point to direct links of this area with Kosovo and parts of southeastern Serbia; however, there are also certain distinctly local elements.

In the territories of municipalities of Novi Pazar, Tutin and Sjenica, under the project: 'Ethno-cultural Relations during the Bronze and the Iron Age in Central Balkan Area', eleven sites were explored, dating from Early Bronze to Late Iron Age.

Glogovnik – Latin Graveyard, a necropolis with eight burial mounds formed randomly, one by another about ten meters apart from each other. The largest of them is the Mound I, 18 m in diameter and 1.7 m in height. Burials in it were performed in some timely separated various intervals. The oldest burial was during the Middle Bronze age, and then between 1000 and 900. During the whole 8th century BC, these parts were inhabited by Dardanians, that is, the population of the same stock as that in the valley of the Raška, Ibar and Sitnica. About the year 700 and in the 5th -6th century BC, burials were performed in the Mound I as well as in other mounds on the site.

Glogovnik – Mounds, on this site explored in 1977/78, stand six mounds of which two are almost flattened by farming. In the mounds, burial places were studied in which funerary equipment (iron spears, swords, and smaller vessels) present so called warriors graves from 6th-5th centuries connected to the Autariats.

Delimedje-Utrina, at the entrance of the village only one mound was explored in which were found graves of cremated dead from the late Bronze and the early Iron Age. Urns from the site belong to the so-called Brnjicka culture, and ethnically to Dardanians.

Sarski Krš, the site on the plateau of a cliff steeply falling to the valley of the Ljudska river, on the right side of the road Sjenica-Ivanjica, and not far away from the crossroads with the road Sjenica – Duga Poljana. The site features the remains of a fortress covering a sizeable area; however, and its large portion was destroyed by quarrying stone for the Road Company from Novi Pazar. Early in the 21st century, 'Telecom' laid a concrete pathway with a metal railing on the leveled route of the ramparts on the south side of the fortification. The pathway leads to the emitter placed at the end of the route of the ramparts. A structure with a metal fence was erected on the north side of the path.

The site was in 1983 researched by the probe and it was determined that the fortress was built in the 6th-5th century BC, and remained in use until 3rd-4th century AD. Explorations on the remaining, partially preserved areas were done during July and September 2007. On the basis of flint stone tools and weapons, stone axes, a stone mould for casting bronze axes and certain types of ceramics vessels, we can conclude that the fortification had been in use considerably before the specified time. On the lower plateau of the fortress the remains were unearthed of a one aisled church measuring 7.50 by 4.90 m dating from the 6th century.
