The extraordinary National History Museum displays fabulous collections concerning Bulgaria's history and civilisation. Each room deals with a specific period: Prehistory (gold treasures of Hotnica and of the necropoles of Durankulak and Varna), Antiquity (treasure of Panagjurište, end of the 4C BC), Bulgarian medieval Empires (632-1395), Bulgarian Territory under Ottoman occupation (1395-1878) and Contemporary History (1878-1946). An interesting ethnographic section is also exhibited.
