Buzludza Monument was built on top of Buzludza in central Bulgaria by the Bulgarian communist regime. It was opened in 1891, then neglected after the fall of the Soviet Union in 1989, and is now deserted. Today, the memorial has been preserved and listed as one of the seven most endangered heritage sites in Europe, and a guard is placed in front of it 24/7, and therefore can no longer be entered, but this does not prevent visitors from visiting and contemplating its unique architecture From outside. In addition, the monument is surrounded by the magnificent Bozludza Park, which is visited by large numbers of visitors to enjoy various outdoor activities.
