Ferme-grenier fortifiée de Coudouneu

The fortified granary-farm of Coudouneu sits above Lançon-Provence, in the Bouches-du-Rhône department of Provence. This Iron Age storage settlement occupies a narrow rocky spur on the southern edge of the La Fare ridge, overlooking the Arc plain and the Étang de Berre. It has been listed as a monument historique since 1998 (reference PA13000026).

What exactly is this site?

Excavations revealed that Coudouneu was never a regular dwelling. There are no hearths and no living quarters anywhere on the site — the whole complex was built for one purpose: storing food. Archaeologists uncovered 154 dolia, large clay storage jars, some holding more than 300 litres, alongside other terracotta containers. The place functioned as a shared granary for the surrounding Gallic community, kept well ventilated to preserve stored goods over long periods.

A stone perimeter wall enclosed the settlement, and the entrance was defended by a fortified gate topped with a wooden platform. Inside stood two elongated buildings, each split into a row of connected rooms with upper floors, separated by a narrow passage. Walls rose from stone foundations, topped with unbaked mud brick.

When was it built, and how did it end?

The granary was raised in the late 5th century BC. It stood for only a short time: in the early 4th century BC it was destroyed in a violent fire. That destruction, paradoxically, preserved the site remarkably well — charred grains of barley, millet and grapes survived intact to the present day. Among the finds, researchers point to what is reportedly the oldest known cultivated garlic clove in France, a detail local guides like to mention.

How do you get there, and what else is nearby?

The best way to visit Coudouneu is a walking loop of roughly 3.77 km, done in about ninety minutes of walking (allow closer to two hours with stops). Elevation gain is minimal and the route crosses open fields on marked paths — easy terrain, suitable for families. The most practical place to leave a car is along the D113 road near Lançon-de-Provence, on the La Fare side, which avoids crossing the busy dual carriageway on foot.

Along the way, besides the granary's foundations and rock-cut steps, the trail passes a restored Chappe telegraph tower with its articulated signal arms — it operated between 1821 and 1855, relaying messages between Vitrolles and Salon. A memorial to Albert Testanier also stands on the route. In spring, especially May, the path is lined with poppies and Spanish lavender, and the ridge opens onto views over the Étang de Berre.

When should you visit?

Spring is the best season — wildflowers and mild temperatures make the walk far more pleasant. Provençal summers get hot, and most of the loop crosses open ground with little shade, so an early start and plenty of water are worth planning for.

Frequently asked questions

Is the site fenced off or staffed? No, it is an open archaeological site reached on foot; there is no permanent staff on location, though the local heritage group Amis du Vieux Lançon occasionally organises guided visits, for example during European Heritage Days.

How is a ferme-grenier different from an ordinary Gallic settlement? The absence of hearths and living quarters shows that nobody lived here permanently — the buildings served only as a communal storage facility for the surrounding population.

How long does a visit take? The full loop takes about two hours on foot, including time to look at the ruins, the telegraph tower, and the viewpoints along the way.

Can you drive right up to the site? No, the road ends at parking along the D113; from there you continue on foot along a marked trail.
