Buzludzha (Turkish: Buzluca - lit. meaning “glacially/icy”) is a historical peak in the Central Stara Planina, Bulgaria and is 1441 metres high. In 1868 it was the place of the final battle between Bulgarian rebels led by Hadji Dimitar and Stefan Karadzha and the Turks.
The Buzludzha Monument on the peak was built by the Bulgarian communist regime to commemorate the events in 1891 when the socialists led by Dimitar Blagoev assembled secretly in the area to form an organised socialist movement. Work on the monument was undertaken by units of the Bulgarian Army assisted by numerous artisans responsible for the large statues and murals. Large images of Lenin and Marx looked over the arena built for state functions and celebrations. Above it all blazed a red star-shaped window in honor of Soviet Russia. It was opened in 1981. No longer maintained by the Bulgarian government, it has fallen into disuse.
