Chapelle Sainte-Agathe de Langon

Chapelle Sainte-Agathe is an early religious building with a rectangular layout and walls made of sandstone and brick. It features a semicircular apse and shows construction techniques from its original Roman period.

The building started as a Roman bath complex in the 4th century and was converted into a church in the 6th century. This transformation reflects the spread of Christianity through existing structures across the region.

The chapel shows how different faiths shaped the space over time, with Roman and Christian elements visible side by side. Visitors walking through can sense the layers of religious practice that accumulated here.

The site is small and easy to explore in a short visit. Plan ahead to check opening times and access conditions, as it is not always staffed and hours may vary depending on the season.

On the walls, remnants of a 4th-century fresco show a classical Roman figure emerging from water. This detail hints at the building's earlier use as a bathing facility before it became a place of worship.
