Description – The small fort 4 of Berchem was part of the first line of forts protecting the city of Antwerp designed by Brialmont. It is a so called Keller fort but should not be confused with the later forts located more to the east and to the south. It was built on a strategic location but was not part of a genuine defensive circle.
Construction & Armament – The fort was built in 1851 featuring earth works (pallisades). Later a brick main building was added roughly the shape of a horse shoe. Initially these forts did not have a saillant towards the city. When later upgrades were added it became a genuine fort but this raised tensions with the city of Antwerp. Fort 4 Berchem had a four pointed star shape with bastions. It featured a wet moat.

Current condition – In 1858 these small forts were completed but by that time it became clear that they could not defend the city of Antwerp. Their location made it impossible to include them in future defensive positions so they were declassified or absorbed in the Grote Omwalling. In the case of Fort 4 of Berchem it was decided to build an arsenal on the eastern part of the site in 1898. The arsenal entered use in 1907). Later the western part became the military hospital of Antwerp (construction started in 1899 and was completed by 1911). When the hospital was disbanded it served as a housing project (Groen Kwartier) and during these works parts of the former fort 4 were uncovered. Remants are no longer visible.
