Dolceacqua is one of the medieval villages of the Nervia valley and is situated along the river of the same name. Its oldest part, dominated by the Doria’s castle, is called Terra and is situated at the foot of Mount Rebuffao. The newest part of the village, called Borgo, is situated on the opposite bank of the river along the road that climbs up the valley.
The Doria castle underwent many transformations. The original feudal plant, protected at the end of the XIIth century by the circular tower, was enlarged and incorporated in a larger ring of walls in the XIVth century. In the Renaissance the castle became an imposing, elegant fortified residence, with new rooms, rich in frescoes and furnishings, that were arranged around the central court; the residence was then completed by impressive defensive devices.
