The site is situated near the Swedish border on an isolated mountain outcropping between lakes Rødenessjøen and Hemnessjøen.

[2] On the night of March 9, 1716, the pyres on the mountaintops announced that Swedish King Charles XII had crossed the border with 1,000 men.

Norwegian troops stationed in the district were assembled by the Basmo commander, Colonel Kruse, who attacked the Swedes in a bloody battle.

Basmo was also in the path of invading Swedish troops during Charles XII's second unsuccessful invasion in 1718.

Today there is a ruin with barely visible defense works and the stone base of the former tower.
