Here, a certain Marie Lorteau (aged 8) is said to have had a conversation with the Virgin. This apparition, although not recognized by the Church, seems to still be celebrated because the site is very well maintained. Returning to cycling, I advise against the trails that head north through the Cailleries wetland nature reserve. Flooded in winter and overgrown with brambles in summer. I won't try it a third time.

I went there to take a dip but the site was littered with rubbish (cake wrappers, chips, candy, tissues, McDonald's bags, pizza boxes, etc.) right down to the water. Exceptional because it was the day after the music festival or just a habit? Sunday was also packed with people (obviously)

Of this important 9th century abbey, all that remains today is the very beautiful abbey church, a priory and the gardens.
