What is often referred to as norway’s largest monument from the Bronze age is to be found a kilometre from St. Olav’s Church at Avaldsnes. Situated on the way to Haugesund, the area is on the left side of the main road. Today only 6 large burial mounds remain. However, maps dating from the 1800s show that there have been many more. A rare gold Bronze age bracelet has been preserved in the largest burial mound, named “Prinsehaug”. the area is also called “Blodheia” – Blood heath – after the great 9th century battle that took place here between "Håkon The Good" and the sons of Erik Bloodaxe.
