Fortifications
The Commandeursbolwerk is located on the west side of Geertruidenberg and dates to 1830 in its present form. Immediately after the capture of Geertruidenberg in 1573, William of Orange ordered the construction of fortifications to begin. The Statenbolwerk, on the north side of the city, is smaller than the Commandeursbolwerk because it is located on a safe side. A single moat provided enough protection on this side of town.
