The History Behind the Name “Gunnuhver”

In Iceland, there is a story behind every valley, canyon, fissure, crack, or mountain and so does Gunnuhver. The haunting story dates back to about 400 years ago. There used to be a woman named Gudrun called “Gunna” who lived in a small house, which was owned by a lawyer named Vilhjalmur Jonsson. The woman was suspected of being a witch owing to the mysterious pot she had in her house, there was always something preparing in it.

Since she was on rent, unfortunately once she couldn’t pay it, and Jonsson took away her cooking pot. With this act, Gunna filled with rage and starved herself to death. Vilhjalmur Jonsson attended her funeral, but as she was taken to the cemetery, the men carrying her heard the threatening voice “No need deep dig, no plans long to lie”. And the very next day Vilhjalmur was found dead with a bruised body and broken bones. And it was believed that Gunna took her revenge. It didn’t end there, she used to intimidate the people living in the peninsula. The locals were frustrated and seek the help from a priest to set a trap for her that ultimately let her fell in the hot spring. Since that time, the hot spring is known as Gunnuhver or Gunn’s hot spring
