Pont Julien crosses the Calavon on the Via Domitia

Below Bonnieux, the three arches of Pont Julien span the rocky bed of the Calavon. Walkers and cyclists use the bridge as they follow the route of the Via Domitia.

A Roman bridge in the Calavon valley

Below Bonnieux, Pont Julien crosses the plain separating the Luberon from the Vaucluse hills. Its large central arch rises above two lower arches. Beneath the pale stone, the river often exposes its rocky bed.

The crossing of the Via Domitia

Built around the turn of the era, the bridge carried the Via Domitia across the Calavon. This major Roman road linked Italy to Spain and served the towns of Provence. The name Pont Julien recalls Apta Julia, now Apt, upstream in the valley.

Listed as a historic monument since 1914, the structure continued to carry road traffic for many years. Cars now use a modern bridge; the ancient crossing is reserved for pedestrians and cyclists.

Three arches and openings for floodwater

The three semicircular arches rest on two piers and the abutments on either bank. The higher central arch gives the deck its slightly humped profile. Up close, rows of limestone blocks trace the curves of the vaults.

The narrower openings above the piers are not passageways. They let some of the water flow through when the river rises, reducing pressure on the structure. The Calavon, often reduced to a few pools in summer, can experience major floods.

The bridge’s limestone and the rocks of the riverbed

The bridge was built with limestone from nearby quarries. Known as molasse or “Pierre du Midi”, this rock formed in a shallow sea around twenty million years ago, from sand and shell fragments.

Around the piers, slabs, hollows and small pools form patterns quite different from those of the cut blocks. Upstream of Pont Julien, towards Apt, the Calavon cuts through the limestone formations around Roquefure. This landscape belongs to the Coulon palaeokarst, an ancient terrain shaped by the dissolution of limestone, whose depressions filled with coloured sands and clays.

The Calavon greenway crosses Pont Julien

The bridge is now part of the Calavon cycle route. Built largely along the former railway from Cavaillon to Apt, this greenway runs through the valley and crosses the Roman structure.

From the bridge, the route continues east towards Apt, or west towards Lumières and Coustellet. For a brief stretch, cycling across the bridge brings the greenway onto the former Via Domitia.

Continuing around Bonnieux and Apt

To the south, the road climbs towards Bonnieux, then towards the Cedar Forest on the heights of the Petit Luberon. To the east, Apt extends the visit through the streets of its old centre and its Saturday morning market.

Further west, Old Oppède offers a walk along cobbled lanes climbing towards the collegiate church and the castle ruins.
