This small church is actually an extension of a 14th-century chapel, which is believed to be the current sacristy. The church in its present form was reportedly completed in 1606 or 1628, depending on the source. In any case, it's a fairly old church for the region.

Built in the 14th century and rebuilt in the 19th century, the Château de la Bretesche stands out for its privileged location on the water's edge. Seeing it suddenly appear as you cycle along the D2 is a splendid sight.

I really didn't understand how to get to the dolmen. The path that was supposed to go there was blocked off. I was able to take a photo over the hedge of the field next door, but it was still very disappointing.

The “Blue Hole” brings together three old granite quarries, at a place called “La Garenne”, on the road to Donges. They were formerly located on the banks of the Loire. They filled naturally with water after their operation ended in 1980. Its name is due to the blue color of the water.
