Sofia's National Museum of Military History is much more substantial than a room of uniforms. Indoor galleries cover Bulgaria's wars and state-building, while the outdoor grounds hold aircraft, artillery, tanks, and other heavy equipment that make the collection feel large and physical.
It is best for travellers who want context on the Balkans beyond churches and Roman ruins. The museum can be dense, but it helps explain how Bulgaria's modern identity was shaped by conflict, alliance, defeat, and uneasy geography.
