Dewsbury Minster lies near the River Calder, traditionally on the site where Paulinus preached. Parts of the church date to the 13th century. The tower houses "Black Tom", a bell which is rung each Christmas Eve, one toll for each year since Christ's birth, known as the "Devil's Knell", a tradition dating back to the 15th century. The bell was donated by Sir Thomas de Soothill, in penance for murdering a servant boy in a fit of rage. The tradition was commemorated on a Royal Mail postage stamp in 1986.
