The Doria castle crowns the hill above the old town — twelfth-century in origin, much extended by the Doria family of Genoese sea-lords who took the village in the 1260s and held it for the next four centuries. The earthquake of 1887 finished the building off as a residence, but the two surviving towers and the curtain wall make a fine ruin and an even better viewpoint.
Climb up through the Terra by the stone-stepped alleys; the gate at the top can be locked outside opening hours, but the ramparts can be approached from outside. The view takes in the whole Nervia valley — vineyards, olive groves, the village at your feet — and the Maritime Alps further north. Modest entrance fee when the gatehouse is staffed.
