A square red sandstone tower standing alone in the middle of the town square, all that survives of a medieval chapel. The chapel itself was demolished in 1836; the tower was kept because it was already a landmark and a clock had been added to it. It is small but disproportionately important — this is the spot where William of Orange's proclamation was first read in 1688.
The tower is not open to visitors but it sits in a pleasant pedestrian area surrounded by cafes and shops, and is the obvious meeting point in the centre of town. A plaque on the wall explains the William of Orange connection. Worth a quick stop on the way through.
