It has 46 rooms distributed in the basement, ground floor and floor . The edifice has a central dome and two lateral turrets. The roof, originally made of sandstone (slate), is currently replaced by galvanized sheet scales (2003-2004). In 1953, the museum recorded 975 cultural objects in the field of archeology, history, ethnography, art, the natural sciences, and a number of 148 documents that were subsequently handed over to the archives.

The museum currently has 21 exhibition halls (12 rooms with porcelain glassware and 9 halls with natural history exhibits), 1 hall for temporary exhibitions and other activities, offices, warehouses and a conservation and restoration laboratory. Contemporary art galleries sum up 651 glass-porcelain objects made at the former glass factory in the city under the auspices of a creative camp between 1985-1988, using the raw sand from Hudesti-Miorcani as raw material. The heritage of natural history sums up 285,151 items of scientific importance from all systematic groups: fossils, rocks, plants, mollusks, corals, crustaceans, echinoderms, insects, fish, batracians, reptiles, birds and mammals. Among the most important acquisitions are the entomological collection Prof. Ioan Nemes, a collection that has been cataloged as one of the first in the country from the scientific point of view and the number of copies collected by a single collector, the exotic pharmacist collection Weber Wilhelm, the collection of birds Exotic (Zair-Africa) Professor Rang Catalin, etc. The museum exchanges publications with museums from the country and abroad, which has led to a substantial improvement of the specialized literature, the museum library having over 6,000 volumes.
