Government can't afford to renovate or knock down structure

Building was left to disintegrate after the fall of the Iron Curtain

The House of the Bulgarian Communist Party, which stands crumbling atop a mountain like an abandoned UFO, has been captured in all its eeriness by a drone.

Built by the Bulgarian Communist regime in 1981, the 14,186,000 leva (£5.3million) Buzludzha Monument eventually became the headquarters for the Party.

After the fall of the Iron Curtain in 1989, the building fell into a state disrepair and the Bulgarian government has neither the funds to renovate or destroy the structure.

As a result, the dome-shaped building and its surrounding monuments – including a large torch – atop the Central Balkan Mountains have become areas of intrigue for urban explorers.

Captured on drone footage is the building from a distance – the large torch can be seen guarding the path that leads to its entrance.

As the drone zooms in on the structure, the extent of the damage becomes clear.

Numerous roof tiles have been stripped away by thieves and leave both the exterior and interior vulnerable to the elements

Other shots focus on the tower that overlooks the flying-saucer that is the Buzludzha Monument – the red star still very much visible despite the colour running somewhat.

Later the drone speeds past the very front of the building and picks out the graffiti.

Above the door in bold red paint is the harrowing message: ‘Never forget your past’ while alongside it is the more satirical: ‘Enjoy Communism’, in the style of the Coca-Cola logo.

The door itself is boarded and bolted shut – a measure that was taken by the Bulgarian Socialist Party after Prime Minister Boyko Borisov transferred them the ownership of the structure in 2011.
