The settlement of Heusden, bordering on the river Meuse (Maas), as we know it today dates back to the 13th century, and started with the construction of a fortification to replace the castle that was destroyed by the Duke of Brabant in 1202. This fortification was quickly expanded with water works and a donjon (castle keep). The city of Heusden received city rights in 1318. The castle of Heusden was the property of successive dukes of Brabant, in 1357 it went over to the counts of Holland.
With the construction of ramparts and moats the castle became located within the city's fortifications, and the castle lost its function as a stronghold. The donjon was now used as a munition depot. A disaster marked the end of the castle of Heusden and caused the economic demise of the city; on 24 July 1680 a terrible thunderstorm hit Heusden, and lightning struck the donjon. Sixty thousand pounds of gunpowder and other ammunition exploded, and destroyed the castle. It took the people of Heusden seven weeks to clear the rubble and debris. The castle was never fully rebuilt. However, the original outlines of the main features were restored in 1987.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
