There has been a banya on or near this site since at least the late 19th century, and this was one of the very few banyas to remain open almost continuously during the Siege of Leningrad. The current circular building, from which the banya takes its name (kruglaya means “round”) dates from 1929. There are separate men’s and women’s banyas, with first- and second-class versions of each. The more upmarket first-class banyas downstairs have separate changing rooms (even if the actual steam-rooms haven’t changed much in decades – if it ain’t broke, why fix it?). Upstairs is more basic, but at 15 rubles for 90 minutes on discount Mondays, not many punters are going to be grumbling about the price, though you’d probably want to keep a close eye on your possessions.
