Sundhöllin (the "Swimming Palace" or Austurbæjarlaug) in Baronsstigur, Reykjavik is the oldest public baths in Iceland. They were designed by the noted architect Guðjón Samúelsson and opened in 1937. The building's exterior is a minimalist white that is almost Art Deco in style with tall narrow rectangular windows. Inside arches on the south side of the pool and the tiled changing rooms are other notable features. The main pool is 25 by 10 metres (82 by 33 ft) and with a depth from 0.9 to 4 metres (2 ft 11 in to 13 ft 1 in). There are also hot tubs, and Guðjón's Hallgrímskirkja can be seen from the sundeck.
