Did you know this tower served not just as a defense but also as a residence? Behind you, the Ruhr was a major trade route back in the day. Interestingly, the castle's moat was never filled with water, a unique feature for such fortresses. To the west, you might spot the Church of Herz Jesu, a reminder of how history and faith intertwine here. The atmosphere invites you to touch the ancient stones and feel the echoes of the past. Let the tranquility and charm of this unique place captivate you.
