Tyrifjorden


The Old Norse form of the name was just Tyri (or Tyrvi). This uncompounded name is also the first element in the name Tyristrand. The name is derived from the word tyri meaning "old/dead pine (wood)", referring specifically to the woods of the western side of the lake. The last element -fjorden (the finite form of fjord) is a later addition.



2011 shooting massacre



On 22 July 2011, an island in the lake, Utøya, was the site of a shooting spree during a youth camp held by the Norwegian Labour Party.
