There is a lake that's a perfect square - Apparently.
Lake Saelen, located in Norway, is the only lake in the world with a perfect square shape, measuring 1.4 kilometers on each side. Its unique shape is due to the lake's geological history, which has resulted in a perfectly symmetrical erosion of the surrounding rocks. This unusual feature makes Lake Saelen a striking natural wonder, attracting geologists and photographers alike. Its square shape has been confirmed by satellite imaging and geological surveys.
