====Military heritage====
The Citadel: Despite its dismantling in the 19th century, the Citadel of Charles V retained the counter-mine galleries which are today buried; the Royal gate and drawbridge, classified in the inventory of historical monuments on 14 April 1932,<ref>{{Base Mérimée|PA00107399}}</ref> flanked on the back of two guardhouses and an arsenal of the 16th century. Among subsequent developments, a powder magazine, housing for officers and a "bombproof" barracks of the 19th century are also noteworthy.

The {{Interlanguage link multi|Château de Selles|fr}} is an old fortified château, which was built in the 11th century. Once isolated by the waters of the Scheldt, it has retained its towers and walls and especially buried ducts. The ducts include much graffiti which attests to the desperation of the prisoners, confined on the orders of the Count-Bishop.
