10. House of the Bulgarian Communist Party – Mount Buzludzha, Bulgaria
Source: darkroastedblend
Maybe the most bizarre and awesome abandoned place on this top 10 list is the House of the Bulgarian Communist Party.
This giant concrete saucer was built on top of one of the most inhospitable peaks of the Balkan Mountains – at just over 4700 feet above sea level. It was here where communist leaders would meet for political rallies and award ceremonies. Seeing this, you can’t help but travel back to a time most would like to forget…however, the Buzludzha monument still stands and serves as a reminder.
