The two towers of St Mary's
Why one is taller than the other.
Two brothers undertook to build the towers of St Mary's church. The elder built faster and his tower rose higher. When the younger realised he would lose, he killed his brother with a knife and then, in despair, finished his own tower lower and covered it with a cupola. On the day the church was consecrated he confessed and threw himself from the tower. The knife is said to hang in the Cloth Hall to this day.
The truth is simpler: the taller tower (82 metres) was the city's watchtower and belonged to the town; the lower one (69 metres) is the church's belfry. The city simply had more money. But look at them at sunset and try not to think about the brothers.
