National Archaeological Museum, Bulgaria

The museum was established as a separate entity in 1893 as the National Museum directed by Czech Václav Dobruský with its headquarters in the former mosque that previously housed the National Library between 1880 and 1893. The museum was officially opened and inaugurated in 1905, as by then all archaeological exhibits previously kept all over the city were moved there, in the presence of Knyaz Ferdinand of Bulgaria and Minister of Enlightenment Ivan Shishmanov. Several additional halls and administrative buildings of the museum were constructed in the following years, which continues to use the historic stone building of the old mosque despite the often unfavourable conditions, notably the humidity in the summer. The museum has five exhibition halls: Central Hall, Prehistory, Middle Ages, Treasure, and a special temporary exhibition. It is managed by the Bulgarian Academy of Sciences.

It is associated with Bulgaria. The record gives 1892 as its date of establishment or first appearance. It forms part of 100 Tourist Sites of Bulgaria and Bulgarian Academy of Sciences. Its recorded seat is Great Mosque of Sofia. It is recorded in the collection of Sofia.

The idea for the creation of an archaeological institute with a museum was conceived among exiled Bulgarian intellectuals in the 1840s, and was among the top priorities for the Bulgarian Literary Society immediately after its establishment in 1869. During the interim Russian administration immediately after the Liberation of Bulgaria, the first steps towards the establishment of a national archaeological museum were taken. In 1892, the institution was de jure established through a decree by the Knyaz, and the assembly of its collections began the next year. Initially it was also known as a "Museum-temple of the Fatherland". Until 1906, the museum included a collection of ethnographic items. By this year however, the collection was becoming so vast that it had to be separated and displayed in a separate institution, which became the Ethnographic Museum of Sofia. Since its foundation, the Museum works actively in cooperation with the Bulgarian Archaeological Society. In 1920 an Archaeological Institute headed by Bogdan Filov was established as an independent institution. It was merged with the museum in 1948 and is under the auspices of the Bulgarian Academy of Sciences ever since. After World War II the joint institution launched a series of archaeological expeditions inside Bulgaria. They conducted studies on a number of sites from the Chalcolithic to the early Middle Ages, which resulted in a number of additional artifacts being added to the museum collection. Today the museum stores a large number of items, although some of them are threatened by damage due to the design of the building, which is characterised by high moisture levels during the summer season.
