This fort, Høytorp fort, the bridge galleries at Fossum bridge and Langnes railway bridge formed the fortress of the Fossum region, the most powerful fortress of the time.

The fort is one of the country's largest inland forts with 1.3 km of tunnels and covered firing positions and 500 m of trenches. In addition, there are spacious rooms for the embarrassment of soldiers and everything they need in a war situation.

Trøgstad fort is the fortification with the longest operational defense system, from its opening in 1917 until "Nike" was closed down in 1990.

This was a barrier fortress and it was to be fought to the last man or until the army had marched up. The fort is divided into two armored batteries. Armored battery A and armored battery B.

All military activity ceased at Trøgstad fort in January 1997 and it is today owned by Indre Østfold municipality. It is maintained as a museum and outdoor area. Volunteers and former officers and soldiers at Trøgstad fort have put in a lot of volunteer work for the fort.
