One of the oldest (and biggest) castles in all of the Netherlands, Hoensbroek Castle is a stronghold of Dutch cultural history located in the pastoral province of Limburg. Over the centuries it's been home to knights, barons, royals, and poets, and was also used as a shelter for orphans after World War II. Given its age, the castle has also seen its fair share of architectural redesigning over the years, and is now a patchwork of historical styles, with an ancient watchtower its last remaining original feature. It is surrounded by a large dramatic moat, which may or may not contain the mythical Hoensbroek Monster.
