Visits to the nave are free of charge (please note church service times!)
There is a charge for the various guided tours, most of which are offered several times a day. In a group, you can discover the interior, the roof, the bell tower, the treasury and various excavations, among other things. There are also tours for children or at night, for example. Further information on the guided tours is available directly from the Cologne Cathedral Visitor Centre (Domforum) or the Cologne Tourism Service Centre, which is also located directly at the cathedral.
