Construction & Armament – This concrete redoubt was constructed between 1910 and 1912. It is considered to be standard redoubt featuring artillery and secured the interval between two adjacent forts. The redoubt featured a wet moat but has only one floor. It is smaller than the design of the Hoofdweerstandstelling redoubt. One cupola was built in front of the redoubt: it had one 75mm gun installed. Two 75mm guns secured the intervals.
Armament – Veiligheidsomwalling Redoubt
- 3x 75mm fortress gun
Current condition – Redoubt XI was completed when the Great War broke out in 1914. It is not known if it participated in any defensive actions. No traces of the redoubt were found on the former site.
