Valkenburg Castle Ruins
Limburg
Valkenburg Castle Ruins stand on the Heunsberg hill in Valkenburg aan de Geul, Limburg, and are unique as the only castle in the Netherlands built on a hill. Founded around 1075 by Gosewijn I of Valkenburg, the castle evolved through multiple rebuilds after repeated destructions in sieges, notably in 1122 and 1672. The ruins today reflect the castle's final destruction during the Franco-Dutch War in 1672, when Stadtholder Willem III ordered its slighting to prevent French capture. The castle was once surrounded by a moat and featured a distinctive ten-sided tower, robust stone walls, and defensive round towers. Beneath the castle lies a network of secret underground passages and the Velvet Cave, historically used for marlstone mining, shelter during World War II, and as a chapel site. The castle's layered history is visible in its architecture, showcasing phases of reconstruction spanning centuries. Today, it is a protected national monument and a significant cultural tourist attraction in the region.
