"The Chapel of the Three Chairs" (cayelles in the local dialect) These are, on Wisques ceramics, the three seats of God, the Son, and the Holy Spirit. The existence of an oratory in the middle of the forest is lost in the mists of time. History even claims that the Druids held their assemblies there.

After being closed for several years, the Saint-Omer train station has been given a facelift. The new, completely renovated building is dedicated to travelers, of course, but also to artists, craftspeople, entrepreneurs… La Station isn't just a station; it's "a space for innovation with a station inside."

A shady spot with this chapel, I used to take a break there 20 years ago with my son. The place is always well-maintained, a tip: see it in March, it's dotted with daffodils 😉.
