The National Historical Museum (Национален исторически музей, Natsionalen istoricheski muzey) in Sofia is Bulgaria's largest museum. It was founded on 5 May 1973 and its first representative exposition was opened in 1984 to commemorate 1300 years of Bulgarian history. The museum was moved to a former governmental residence in 2000 and currently stores and owns over 650,000 objects connected to archaeology, fine arts, history and ethnography, although only 10% of them are permanently exhibited.
