Fortifications
Although Antwerp was formerly a fortified city, nothing remains of the former enceinte or of the old citadel defended by General Chassé in 1832, except for the Steen, which has been restored. Modern Antwerp's broad avenues mark the position of the original fortifications. After the establishment of Belgian independence, Antwerp was defended by the citadel and an enceinte around the city. In 1859, seventeen of the twenty-two fortresses constructed under Wellington's supervision in 1815–1818 were dismantled and the old citadel and enceinte were removed. A new enceinte 8 miles (13 km) long was constructed, and the villages of Berchem and Borgerhout, now boroughs of Antwerp, were absorbed within the city.
This enceinte is protected by a broad wet ditch, and in the caponiers are the magazines and store chambers of the fortress. The enceinte has nineteen openings or gateways, but of these seven are not used by the public. As soon as the enceinte was finished eight detached forts from 2 to 2 ½ miles from the enceinte were constructed. They begin on the north near Wijnegem and the zone of inundation, and terminate on the south at Hoboken. In 1870 Fort Merksem and the redoubts of Berendrecht and Oorderen were built for the defence of the area to be inundated north of Antwerp.
In the 1870s, the fortifications of Antwerp were deemed to be out of date, given the increased range and power of artillery and explosives. Antwerp was transformed into a fortified position by constructing an outer line of forts and batteries 6 to 9 miles (14 km) from the enceinte.
