Main image

Seljordsvatnet is a freshwater lake in Seljord municipality in the Telemark area of southern Norway. It is known locally for the folklore of a lake serpent colloquially called Selma.

Recreational activities on and around the lake include angling and boating, and the shoreline is used by residents for leisure. The small size and proximity to the village of Seljord make it a local, rather than a regional, attraction.

The lake and its legend have been part of local culture for centuries, referenced in regional stories and press accounts. There is no single formal archaeological site on the lake itself, but the area around Seljord has long been settled.

The lake sits within Seljord municipality in Vestfold og Telemark, immediately adjacent to the village of Seljord and accessible by local roads.

  • Local legend: The lake is associated with a longstanding local sea‑serpent legend known as Selma.

Tips for Visiting Seljordsvatnet #

  • Visit the town of Seljord to see the wooden 'Selma' sculpture and local museum exhibits about the lake's folklore.
