Pierre-de-Herpin lighthouse

Pierre-de-Herpin lighthouse stands on rocky cliffs near Cancale, rising about 24 meters above the shore. The structure features a stone base with a white painted tower that remains visible to maritime traffic across the bay.

The lighthouse was built in 1882 to warn ships away from dangerous rocks along this Breton coast. It was part of a broader effort to improve maritime safety in the region during the 19th century.

The lighthouse embodies the maritime traditions that shaped this coastal region and remains a focal point for understanding the area's seafaring heritage. It reflects how navigation and fishing defined the identity of local communities.

The lighthouse is best viewed from the coastal path, especially from Pointe du Grouin where several lookout points offer clear sightlines. The walking route is straightforward, but expect uneven terrain and coastal winds.

The structure still serves active mariners as a navigation aid and has maintained its original guiding function for more than 140 years. Despite modern technology, it remains an important reference point for ships navigating these waters.
