Timothy sez, "This is a link to some photos I have took of Buzludzha (pronounced Buz'ol'ja) a very remote building in the Balkan Mountains. It is Bulgaria's largest monument to Communism which was left to ruin after the revolution in 1989. An incredible 70 metre tall, 1970's 'flying saucer' perched precariously in the snow on a ridge at 1500m. Full of beautiful communist mosaic frescos and an amazing central atrium complete with giant golden hammer and sickle. It took 6000 workers 7 years to build. I managed to fly over it in a microlight in mid winter to get some interesting pictures too. Such an amazing place."
