The construction of the cathedral that dominates Torun's skyline started in the 1260s and took 200 years to complete. The star attraction is the Tuba Dei, the oldest medieval bell in Poland, cast in 1530. It's also one of the 11 historic bells in Torun that survived looting and recasting into weaponry. In the past, Tuba Dei's peal heralded the arrival of popes and Polish kings. A twirl up the claustrophobic spiral stairway gets you a view of the bell and the added bonus of postcard views of the Old Town Square and the river. The cathedral's 15th-century clock has a single hand, referred to as Digitus Dei (God's Finger). The ongoing renovation work in the chapel is expected to be completed by 2012.
