Apennines

"His comings and goings made no change at the villa, and yet there was no one there but felt easier to think his yellow face was on the far side of the Apennines, unless perhaps it was the chaplain."[1]

The Appenines are a mountain range in Italy. They are " bordered by narrow coastlands that form the physical backbone of peninsular Italy. From Cadibona Pass in the northwest, close to the Maritime Alps, they form a great arc, which extends as far as the Egadi Islands to the west of Sicily. Their total length is approximately 870 miles (1,400 kilometers), and their width ranges from 25 to 125 miles."[2]
