Translated: “Saki. Patients in mud baths”.
This photo was taken at the Saki Sanatorium in Evpatoria, Russia. It is dated circa 1920, which makes it one of the Soviet Union’s many workers’ spas. This is a place where hardworking citizens were required encouraged to rest as part of the 1922 Labor Code. [1]
The visitors could expect various spa treatments at no cost, but they were not allowed to drink, dance, or be loud. [2] Bummer.
