Gaffer - Lanildut
Emmanuel Berthier



Europe's leading seaweed port

In Lanildut, sailboats, fishermen and seaweed harvesters are busy at all hours of the day and night. Today, a well-laden seaweed boat returns to port, and a little further on, a second one leaves the quay. The place is free and seaweed unloading is about to begin.

The trucks leave the port, bound for the processing plants for the food, pharmaceuticals, cosmetics, textiles and paper industries that use their gelling agents (alginates). Want to find out more? The Maison de l'algue offers seaweed identification and cooking workshops. Visit the Maison de l'Algue: the building offers a fantastic view of the port.

What is an Aber?

Aber Ildut is the smallest of Finistère's 3 Abers. "Aber" is a Celtic word for an estuary into which the sea rises deeply at high tide. The calm of this green setting, wooded with pedunculate oak and willow, contrasts sharply with the invigorating walks exposed to the winds of the open sea. The Aber lends itself to a wide range of activities. Kayak or paddle, walk or hike, discover this astonishing environment.

Le Rumorvan

Typical coastal village

Lanildut's history goes back to the first half of the 17th century. To immerse yourself in this history, head towards Rumorvan and discover the beautiful, rich stone houses of the shipowners or coasting skippers known as "maîtres de barque". The architecture of these homes is codified: Laber granite walls, dormer windows, half-moon chimneys...

l'obélix de Lanildut


Laber granite

Replica of the Louqsor obelisk

Aber Ildut granite, known as "de Laber", has been renowned since prehistoric times. From the Kerloas menhir to the Quai de Londres, from the Cordouan lighthouse in Gironde to the base of the Concorde obelisk in Paris, the exploitation of this rock, so characteristic of the region, has left numerous traces along the coast. It was from Lanildut that the base of the obelisk was loaded into the hull of the Luxor, which was sawn and rebuilt on the shore a few days later.

Château de Kergroadez


Brélès at a crossroads

On the heights of Aber Ildut

The small village dominates the surrounding area, in particular the bottom of the Aber Ildut. The first thing you see is the octagonal openwork spire of the church tower, then the roofs of the rich granite houses with their English-style chimneys. This mineral, flower-filled village is architecturally rich. Don't miss Notre Dame church, built by the lords of Kergroadez in the 15th century, with its triumphal arch and crosses finely carved in kersanton.

history & culture

The columns of justice

A monument unique in the region

Macabre no doubt, but an integral part of history, the columns of justice are located just a few hundred meters from the Château de Kergroadez. It was a long way to the gallows for the condemned. Today, it's an ideal spot for a family picnic before a visit to the château, and the starting point for a hike or a wooded walk sheltered from the sea winds.

The menhirs of Kergadiou

Witch's Menhirs

Around the bend in a dirt track, you'll spot them, one standing, the other lying in the middle of a field. Legend has it that one of the menhirs was stolen from a witch in Ireland. Very angry, she threw a second menhir in the direction of the first, but missed. It crashed into the ground a few metres from its target. 


Seafood, local cuisine

Treat yourself to a gourmet break on the banks of the Aber Ildut, where delicious dishes await you in a bucolic setting.
