Drenched into its identity as a mythological city related to the Mahabharata and still carrying the name, Viratnagar has yielded a number of historical relics through a course of archaeological explorations and excavations carried out during the 19th and 20th century. This region, including the three hillocks—Bijak-Ki-Pahari, Ganesh-Ki-Dungri and Bhim-Ki-Dungri—located within the inner range of hills, has unearthed material relics relating to prehistory and continuing up to the medieval period which is presented in a museum set up by the state government under the Department of Archaeology and Museums. Called Rajkiya Kala Dirgha or State Museum, Viratngar, the space was opened in 1987 near Ganesh-Ki-Dungri as part of the ongoing efforts of the state in the area of museums.

The museum primarily comprises of two galleries which showcase microlithic tools from the prehistoric period, Painted Grey Ware (PGW), Northern Black Polished Ware (NBPW) and other associated terracotta pottery remains, punch-marked, historical and medieval coins, iron artefacts, pieces of polished sandstone umbrella from Mauryan period, Teerthankara sculptures from the late medieval period and other significant relics which displays a rather continuous history of Viratnagar. Some of the coins and other artefacts discovered from this region are also part of the collection displayed in Albert Hall Museum and Alwar Museum.

The museum currently does not offer any guided tours, workshop, library or conservation lab services. It is open on all days except Mondays and public holidays.
