The National Archaeological Institute with Museum in Sofia is Bulgaria’s principal institution for the study and exhibition of archaeological heritage. Established in the late nineteenth century and administered by the Bulgarian Academy of Sciences, the museum houses artifacts spanning prehistoric settlements, Thracian civilizations, Greek colonies, Roman provincial culture, and the medieval Bulgarian states. The museum is located in a former Ottoman mosque, the Büyük Mosque, constructed in the late fifteenth century during Ottoman rule in Sofia. Since the early twentieth century the building has served as an archaeological museum, displaying a wide range of artifacts including Thracian gold treasures, Roman inscriptions, medieval objects, and materials uncovered through archaeological excavations across Bulgaria.

Construction of the Büyük Mosque
15th centuryThe building that houses the museum was constructed around 1474 during the early Ottoman period in Sofia. Known as the Büyük Mosque, it served as one of the city's principal Islamic religious buildings following the Ottoman conquest of the region in the late fourteenth century.
Transformation into a Museum
19th centuryAfter Bulgaria achieved autonomy from Ottoman rule in 1878, the mosque was repurposed as a cultural institution. In 1892 the Bulgarian government established the National Archaeological Museum to preserve and display artifacts uncovered during archaeological research throughout the country.
Development of Archaeological Research
20th centuryThroughout the twentieth century the museum expanded its collections as systematic archaeological work increased across Bulgaria. Excavations at Thracian tombs, Roman cities, and medieval fortresses contributed significant artifacts, many of which were transferred to the museum for preservation and public display.
Modern Role
Late 20th century – presentToday the museum operates under the National Archaeological Institute of the Bulgarian Academy of Sciences. It functions both as a research center and as a national museum presenting Bulgaria’s archaeological heritage from prehistoric periods through the medieval era.
