Kollentrollet is a 6,7-metre statue located at Gratishaugen overlooking the Holmenkollen Ski Jump.

"A troll am I. Big and tall. I sing in one of my songs. For I am big and tall. When you see me sitting at Gratishaugen, I measure almost 7 meters. Big and tall may sound dangerous, but that's not the case. I am a good troll. It is the famous Norwegian sculptor Nils Aas, who brought me here. I am made of concrete, and I guess I do look a lot like the trolls you'll find in the Norwegian folk tales collected by Asbjørnsen and Moe."
