Phare d'Aiguillon

Phare d'Aiguillon stands on the Pointe de l'Ève, on the northern shore of the Loire estuary, right in front of Saint-Nazaire. It is one of the oldest navigational landmarks in the region, with a tower dating back to 1756.

Why was the lighthouse built?

In the mid-18th century, Nantes was one of the busiest trading ports in the Kingdom of France, driven largely by commerce with the Antilles. The growing volume of shipping made it essential to mark the difficult entrance to the Loire estuary more clearly, particularly around the treacherous Banc des Charpentiers sandbank. On the orders of the Duke of Aiguillon, then governor of Brittany, naval engineer Mangin built a tower in 1756. Paired with the Tour du Commerce (the former Saint-Nazaire lighthouse), it created a leading line that helped ships line up safely as they entered the river.

How did the lighthouse evolve?

The structure was upgraded several times as lighting technology improved. In 1830 it received a Fresnel lens system producing a fixed white light — a major leap in range and clarity for ships navigating at night. In 1857 the tower was raised, and a keeper's house was built alongside it, confirming the site was permanently staffed at the time.

The 20th century brought further changes: the lighthouse was electrified in 1935, replacing earlier light sources, and it was fully automated in 1976, ending the need for a resident keeper.

Who was its most famous keeper?

Among those who served at Aiguillon, one name stands out: Narcisse Pelletier. This French sailor survived a shipwreck off the Australian coast and spent seventeen years living among an Aboriginal clan before eventually returning to France. From August 1876 to spring 1878, he worked as keeper at the Phare d'Aiguillon — a remarkable footnote that still draws interest from historians and maritime enthusiasts alike.

What will you see on site?

The lighthouse sits on a low, open point with clear views over the Loire estuary, the ships moving in and out of the port of Saint-Nazaire, and the opposite bank of the estuary. The setting combines coastal scenery with a strong sense of local maritime history — it's worth pairing a visit with the other lighthouses near Saint-Nazaire, such as Kerlédé and Villès-Martin, to see different stages in how the Loire estuary was marked for shipping over time.

The tower itself is not open to visitors on the inside, but the surrounding point makes for a pleasant walk, good birdwatching along the shore, and a scenic subject for photography, especially at sunset when the light hits the tower from the land side.

How do you get there?

Phare d'Aiguillon sits on the northern shore of the Loire estuary, within the Saint-Nazaire municipal area, and is easily reached by car or bike from the town centre. The site forms part of a wider coastal walking route linking several viewpoints over the estuary.

When should you visit?

Late afternoon offers the best light, with the sun illuminating the tower from the land side and good visibility of river traffic. Spring and summer are best for longer coastal walks, while autumn and winter bring stronger Atlantic winds worth preparing for.
