Sorry about the kind of headline that sounds like a rejected Alan Partridge documentary, but I promise the video is pretty cool.

Two skiers explore the ruins of the House-Monument of the Bulgarian Communist Party, a building dedicated to the ideology and government which ruled over the country from 1946 to 1990. In addition, the House-Monument was intended to be a symbol of national pride, with construction financed by donations from the population, but was one of about 150 tributes to communism scattered around the country.

Completed nine years before the government fell, the building has since fallen into decay because of harsh weather conditions. You can read much more about it here and shouts to these YouTubers for checking the building out...
