Why go
Tskaltubo was the Soviet Union's premier radon-cure sanatorium complex, where Joseph Stalin maintained a private dacha and workers received state-funded treatment for ailments in its naturally warm, mildly radioactive mineral baths. After the USSR collapsed, the sprawling ensemble of twelve ornate sanatoriums—designed in ornate Stalinist and later modernist styles—emptied almost overnight. Today, these decaying palaces of health stand as perhaps the world's most atmospheric ruinscape: marble halls colonized by bats, mosaic ceilings peeling above empty pools, and the occasional returning pensioner still seeking the famous waters. It is Soviet utopian architecture at its most haunting and grandiose.
