The Fort near Spijkerboor is the only Defence Line fortress that has a gun turret that can be visited. Its two 105 mm calibre guns had a range of 10 kilometres (6.2 miles). For short periods of time the two storey fortress served as a convict prison: during the war it was a military prison and after the war Dutch collaborators with the German occupier were locked up in the fort. The barred windows date back to those days, as do the murals in the postern. From 1947 onwards, drafted soldiers who refused to serve in the Dutch Indies were jailed in the fortress. Recently the stronghold was restored. The Fort near Spijkerboor was constructed for the defence of the dikes and roads that ran along two canals, the Beemsterringvaart and the Noord-Hollands Kanaal. Construction of the defendable earthwork was completed in 1895. The shellproof building was finished in 1911. The fort was the main stronghold of the northern part of the Defense Line of Amsterdam.
