From the beginning, the spa was taken care of by TaTU and TaUS (Tampereen Uimaseura), but from 1960’s, solely TaTU has taken care of Rauhaniemi. During those times there was also a swimming facility at Palomäki, that both groups had been looking after as well.
The saunas were built at Rauhaniemi in 1957, around the same time that Pyynikki’s swimming hall was built. Saunas became popular and thanks to saunas, people were able to swim during autumn as well. Later the dressing rooms became heated and that was when winter swimming became possible. At the waters of Rauhaniemi, many residents of Tampere have learned to swim.
