Long distance walkers to Nidaros Cathedral now receive a new diploma. It has been given the name The Olav Letter (Olavsbrevet). Trondheim has now a pilgrim diploma, just like Jerusalem, Rome and Santiago de Compostela.
The Olav Letter is given as a confirmation that one has walked along the pilgrim way to Nidaros. To qualify you must have walked the last 100 kilometers into Trondheim. To document your trip you use The Pilgrim's Passport.
