This was originally a well, marked by a wooden cross; the water was famous for treating rheumatism. A chapel was built more recently on this site; small square plan construction opened on one side by a basket-handle arch surmounted by a small granite cross as a keystone. Inside are some objects bearing witness to the passage of pilgrims through the ages: porcelain cup, votive, candlestick... At the rear of the building, a niche houses several statues of saints.
