Dovrefjell is a mountain range in central
Norway that forms a natural barrier between
Eastern Norway and
Trøndelag, the area around
Trondheim. As a result, it has been heavily trafficked during and probably preceding historical times. Several mountain inns were established in the Middle Ages to house pilgrims traveling to Trondheim, and there are even ruins of an old
leper colony in the northern area of it. The main south-north highway (
E6) and railway
Dovrebanen in Norway runs over Dovrefjell. The highway is a year-round highway but is at rare occasions closed for short periods during heavy winter weather conditions.
