Tskhaltubo was one of those spa resorts on the so-called Soviet Riviera. Eventually, construction on its 18 sanatoriums began in the 1920s, and by the 1980s, trains drove in daily from Moscow. Since the 18th century, several foreign researchers gave word of the healing properties of the Tskaltubo springs. Meanwhile, in 1920 the territory of Tskaltubo became state property, and it acquired the function of balneology resort. Balneotherapy is the treatment of disease and medical conditions by bathing in mineral-enriched water. In 1953, Tskaltubo became an important spa-resort during the Soviet times. Tskaltubo mineral water cures both diseases from the limbs, peripheral nervous system and skin. It also cures cardiac and vascular diseases. The water emerges at a comfortable temperature for bathing, in fact it is directly transferred from the springs to the baths, without cooling or heating.
