Fort 5, Military fort in Edegem, Belgium

Fort 5 is a brick and sandstone fortification located in Edegem with extensive grounds that form part of a larger defensive complex. The structure displays typical 19th-century military design with ramparts, casemates, and various functional spaces arranged across the site.

Fort 5 is one of eight forts of the Brialmont Belt around Antwerp, designed by then-captain Henri Alexis Brialmont. Construction began in 1859 and the belt was completed in 1864; Antwerp had been chosen as the National Redoubt in 1859. Each fort covered about 30 hectares. The forts were soon outmatched by new artillery, and on 8 October 1914 Fort 5 came under German fire.

Since 1990 the inner fort has been restored and now houses the Simon Stevin Flemish Fortification Centre. Since 2013 a local initiative runs a coworking space called 'het Bolwerk' inside the fort, meant to encourage entrepreneurship and support the local economy.

The grounds are freely accessible from 6.45 to 21.00, with walking paths laid out across the site. The fort buildings themselves are closed and can only be entered with a guide; Erfgoed Edegem's historical guides lead tours of the domain. Fort 5 and the Hof ter Linden estate together form a green area of nearly 90 ha.

Fort 5 is one of the Antwerp forts listed under the EU habitats directive because they are important bat hibernation sites. The fort is also home to the Simon Stevin Vlaams Vestingbouwkundig Centrum, and since 2013 the inner fort has housed the coworking space 'het Bolwerk'.
