[3][4] The battery is designed as a long arch with a low parapet with ammunition niches and shallow covered chambers for the crew.
From the battery there is a broad view of the center of Fetsund and the east side of the Glomma River.
The purpose of the battery was to prevent any military advances southward from Sørumsand or northward from Fjellsrud crossing the Glomma over the Fetsund rail and road bridge.
[5] On September 13, 1905, mobilization orders were issued, and the Fetsund and Høgås batteries were manned with 1,450 men from the Valdres Battalion and a squadron of militia dragoons.
German soldiers were quartered at the Vilberg farm, located between the battery and the depot camp.
It is not clear whether the site was originally planned for storing bridge materials when it was established, or if this use of the depot camp was made at a later date.
This pontoon bridge was previously stored over an extended time at Stasjonsstranda next to Fetsund Station.
