Neo-Gothic style church built in 1877, it replaces an old 11th-century Romanesque church that had become too small and dilapidated. Interesting small built heritage in the village center.

Une petite baie qui fait partie de la grande baie de Pont-Mahé. La plage se découvre largement à marée basse et semble prisée des pêcheurs à pied locaux.

Not necessarily the most suitable beach for swimming, but the view of the rocks and the bouchots is worth the trip.

A very beautiful city, both for its iconic port at the foot of the rocks and for the old town and its charming alleys.

The port is very beautiful but even if you have to climb, the old town is also worth a visit
