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."

The church of Clairmarais was built in 1873, near the ruins of the former Cistercian abbey that gave the village its name. It replaced the abbey church that was destroyed during the French Revolution. The church is dedicated to Saint Bernard of Clairvaux, the spiritual father of the abbey. Today it is a landmark in the village and a silent witness to the religious heritage of this region. Note the coloured memorial to the dead next to the church.
