Balagne's smallest village has some pleasant surprises in store for you. Costa is a wonderful place, full of old stone houses, alleyways and arches. The only way to visit is on foot.
Next to the town hall, the Malaspina House, a beautiful residence built in the 17th century, overlooks one of these vaulted passages. Take your time in Piazza Cumuna. Stop in front of the church of San Salvatore and enter to admire its paintings, olive tree statues and beautiful organ.

And if you feel like quenching your thirst, push on to the 17th century washhouse where the water gushes out of the fountain with a purity equalled only by its freshness.
