Construction began on 23 January 1974 under architect Georgi Stoilov, a former mayor of Sofia and co-founder of the Union of Architects in Bulgaria.
The building exemplifies the futurist architecture common to many state-constructed communist buildings. It is no longer managed, and is closed to the public as it is considered dangerous.
The monument was abandoned after the fall of the Soviet Union in 1989 and now lies derelict.
There is a proposal by The Buzludha Project to architecturally preserve the monument and turn the building into an interpretive museum of Bulgarian history.
