Kasteel Wolfrath in Sittard-Geleen

You're standing at Wolfrath Castle, close to the village of Holtum in Limburg. First, look at the corner tower. It stands exactly where the two wings meet at a right angle. On top sits a bell-shaped roof with a tiny dome. In the main wing you'll see the entrance gate, framed in bluestone and crowned with three gilded balls in niches. You reach it over a brick arched bridge across the moat.
