This glamorous Art Deco swimming facility built in 1926 may look the former playing ground of silent movie starlets, but Amalienbad was actually a public health project of the socialist Rote Wien (Red Vienna) administration. And what luxury for the commonwealth: floor plans based on ancient Roman baths, interiors lavish with Art Deco flourishes, mosaics and columns, and numerous saunas were all laid out with care and detail.

Let it be known that the Amalienbad folk take their sweating seriously. Especially popular with the Viennese is the Finnish sauna, though if it’s too crowded, the steam bath, whirlpool or bio-sauna all make for excellent alternatives. Massages also available. And once you’re all cleaned up, cool down with a scoop at Tichy’s Ice Salon across the street.
