Apennine fells

The Apennine fells is a ridge of fells stretching over 600 miles from the north to the south of Italy along its eastern shore, going the whole length of the headland, and making, as it were, the backbone of the land.

The name most likely comes from Celtic pen, meaning a fell, and thus is linked to the English Pennines. The word was at first given only the the northern half of the ridge.
