Close your eyes and picture a charming medieval Italian village, perched on a hill, church bells marking the hours, a hazy spread of patchwork fields fading into the distance. Well, that"s the ancient village of Arrone. (On second thought, we probably didn"t need the photo.) Arrone looks over the Valnerina, a valley carved by the River Nera, which twists its way through Italy"s scenic Umbria region, known as the Green Heart of Italy.
