the shrine in nidaros was mentioned in historical sources already in 1075 - in the works of adam of bremen " bremen's gesta pontificum hammaburgensis ecclesiae ." there are also the various accounts for pilgrimage routes to nidaros, including coastal pilgrim way: "if you sail from aalborg and vendsyssel in denmark, you come to viken in a day, which is a town in norway (probably oslo). from there you hold left and sail along the coast of norway and on the fifth day you reach the city trondheim. one can also get an other road, which leads from the danes in their scania overland to trondheim. but this road over the mountains takes longer, and since it is dangerous, it is avoided by the pilgrims.» arriving by sea by kystpilgrimsleia- constituted thus, according to adam of bremen, the most used artery to nidaros, although the sea route was also dangerous with changing weather and pirates. both norwegian and foreign pilgrims flocked here, either to travel all the way to nidaros, or to visit many of the local shrines.
