What the Museum Is

The National Polytechnical Museum in Sofia showcases Bulgaria’s scientific and technological heritage, from the 19th century to the digital era. Its collection includes more than 22,000 artifacts, including timekeeping devices, vintage automobiles, early computers, and photographic equipment.

The museum is at 66 Opalchenska Street and is accessible by public transport. It offers facilities for visitors with disabilities and is a cultural stop for visitors exploring Sofia, including those visiting landmarks such as Alexander Nevsky Cathedral.

History and National Significance

Founded on May 13, 1957, the museum was initially managed by the Bulgarian Academy of Sciences before being transferred to the Ministry of Education and Culture. It became a national museum in 1968. Its first director, Eng. Alexander Valchev, played a key role in shaping the collections.

The museum is one of Bulgaria’s “100 National Tourist Sites,” attracts approximately 30,000 visitors annually, and serves as the headquarters of the Bulgarian National Committee of the International Council of Museums (ICOM). Its mission is to preserve and showcase Bulgaria’s technological progress and encourage public engagement with science and technology.
