I will never forget the wind up on the peak. The monument remains a piece of art and extraordinary vision regardless of what ideology one believes. (Inside the building, mosaics that cover approximately 510 square meters of space commemorate the history of the Bulgarian Communist Party. The mosaics were built with 35 tons of cobalt glass. Today 20% of them have been destroyed due to age and vandalism. On the outer ring of the monument, mosaics were built with natural stones gathered from rivers across Bulgaria. These mosaics have also mostly vanished due to natural causes. https://en.m.wikipedia.org/wiki/Buzludzha_monument)
