chapelle Sainte-Marie de Trévans

Chapelle Sainte-Marie de Trévans is the ruin of a former monastery tucked into the Gorges de Trévans, in the commune of Estoublon, in the Alpes-de-Haute-Provence department. Its weathered stone remains sit on a rocky spur above the ravine carved by the l'Escale river, hemmed in by limestone cliffs and Mediterranean scrub — a site as historically layered as it is scenic for hikers passing through.

What's the story behind the ruins?

A monastery was founded here in the 13th century by Jacques Apérioculos, lord of Gaubert and Trévans. It was originally dedicated to Saint-André-du-Désert and took in Carmelite monks whom King Louis IX brought back from the Holy Land following the Seventh Crusade in 1254. The community flourished for a time, but by the 15th century it had been reduced to a modest rural priory. In 1450, the Bishop of Riez, Jean Faci, took over the site in an attempt to re-establish a monastery there. The building was ultimately caught up in the Wars of Religion — attacked repeatedly, it was finally abandoned in 1575 when the Carmelites relocated to nearby Estoublon.

What will you actually see there?

What remains today is a genuine ruin — fragments of wall fused into the rocky ridge, with views opening onto the gorge and the cliffs surrounding it. The setting feels wild and untamed rather than curated: limestone gorge walls, dense scrub typical of southern France, and a quiet broken only by birdsong. This is a stop for travelers drawn to the combination of history and raw landscape, not a restored monument with interpretive panels.

How do you get there, and can you explore the ruins freely?

The ruins sit at the heart of the Gorges de Trévans, reached on foot from trails starting at the Parking des Gorges de Trévans near Estoublon. Since February 2021, the entire gorge area has held the status of a réserve biologique intégrale (integral biological reserve), meaning access is limited strictly to marked hiking trails — leaving the path or climbing onto the ruins themselves is not permitted. Keep this in mind when planning a visit: it's a protected natural area with a historical feature, not a site for free exploration.

When's the best time to visit?

Spring and autumn offer the mildest Provençal temperatures and quieter trails. In summer, the rocky gorge heats up quickly with limited shade, so an early start and plenty of water are essential. Winter access can be affected by weather, but the stillness and starkness of the ruins take on an added atmosphere during the colder months.

Frequently Asked Questions

Can you walk right up to the monastery ruins? The site lies within an integral biological reserve, so movement is restricted to marked trails only — you cannot leave the path or climb onto the ruins themselves.

How long does the hike from the parking area take? Depending on the trail chosen and your pace, reaching the ruins typically takes one to two hours each way over uneven, rocky terrain.

Are there other sights worth combining with a visit? Yes — the Gorges de Trévans include several viewpoints and loop trails, including one toward the hamlet of Valbonnette, making it easy to pair the ruins with a longer scenic hike.

Is this a suitable outing for families with children? Given the rocky, uneven terrain and the site's protected status, caution is advised — older children used to hiking can manage it, but sturdy footwear and supervision are essential.
