Saint-Morillon brings together the landscape along the Gât-Mort and a history that can be read in its bridge, church and château. When planning a stay, visitors can choose between two distinct highlights: nature trails and historic buildings.

River, protected area and trails

The Gât-Mort flows through the village. Part of the municipality lies within the Natura 2000 site “Réseau hydrographique du Gat Mort et du Saucats” (FR 7200797). These two details describe different geographical scales: the river flows through Saint-Morillon, while the protected-area designation covers part of the municipality.

The Boucle des anciennes landes runs mostly along country paths, through former heathland once used for sheep grazing, and through the Gât-Mort valley. The landscape and its former land use are connected here: the route’s name refers to the heathland of the past, while the trail also passes through the river valley.

There is also a 600-metre nature walk at the Prairie du Gât-Mort. According to the municipal visitor information from April 2025, the municipal land used for this walk is open to visitors; check local access before your visit. At 600 metres, the walk is a compact nature outing at the Prairie, while the Boucle follows country paths and passes through the valley.

To take the Boucle des anciennes landes, follow the road opposite the Church of Saint-Maurille that runs to the left of the church. Check trail conditions and local signage before setting out.

Bridge, church and historic furnishings

When it was built in 1838, a single-arch stone bridge symbolised the reunification of the two sides of the village. The Church of Saint-Maurille dates from the 12th and 13th centuries. Its apse, choir and transept chapels were listed as historic monuments in 1925.

The church furnishings include a carved, gilded wooden high altar from the first quarter of the 17th century. Its movable statuettes depict Saint Peter and Saint Paul; the altar was protected as a movable cultural asset in 1954. A restored wall painting from the early 18th century brought the coat of arms of the Montesquieu family back into view. The church’s history thus spans the construction of the building in the 12th and 13th centuries, the early 17th-century high altar and the early 18th-century wall painting.

The Château de Bel-Air is privately owned and listed as a historic monument. Its protected features include the façades, roofs and interior, as well as a water basin and statues in the park. The listed features therefore extend beyond the building itself to elements of the grounds. The château was also classified as a protected site in 1973.
