According to Laxdæla saga, Guðrún Ósvífursdóttir used to dwell by a geothermal pool in Laugar in Sælingsdalur. The pool is mentioned in Sturlunga saga and it seems to have been used a great deal.
The pool is believed to have been destroyed in a landslide. In 2009 a new pool was built near to the location where the old pool is thought to have been situated and named Guðrúnarlaug.
A changing facility, referred to as a “house of modesty” in Icelandic, was also built at the same time.
