National Archaeological Institute with Museum

The National Archaeological Institute with Museum stands on ul. Saborna in central Sofia, Bulgaria, next to the Presidency and the Largo. It is the country's main archaeological museum, established in 1892 and housed since 1905 in the former Great Mosque (Buyuk Dzhamiya), a large Ottoman building from the late 15th century, built during the reign of Mehmed II and commissioned by the Grand Vizier Mahmud Pasha. The domed, nine-cupola structure was converted into a museum after the Liberation and has been the institution's home for more than a century.

The museum's collections cover Bulgarian lands from the Stone Age to the Middle Ages. Highlights include Neolithic and Chalcolithic pottery and figurines, Bronze Age objects, rich Thracian finds such as gold jewellery, helmets, greaves and other weapons, and Greek and Roman sculpture, inscriptions and bronzes. Medieval Bulgarian exhibits include ceramics, jewellery, inscriptions and architectural fragments, many from the early capitals of Pliska and Preslav. Among its best-known artefacts are Thracian gold items and finds from tombs.

The building is a major exhibit in its own right. The prayer hall with its grid of domes and thick walls provides a dramatic setting, though the architecture and lighting can be dim compared with modern galleries. Some galleries are arranged thematically by period, while others display single collections. The museum is closely linked with the Archaeological Institute, which carries out excavations and research across the country, so displays often reflect recent finds.

The museum has undergone a series of restorations and refurbishments, including conservation of the historic building, and parts of the museum have at times been closed for works. Visitors should check the website or inquire locally about the current status of galleries. Its central position makes it a natural stop together with the Serdica ruins, the Rotunda of St George and the Presidency.
