Abbey of Mont-Saint-Éloi

The two towers of Mont-Saint-Éloi dominate the Arras region. They can be seen from afar. They shape the landscape of the Artois plains. They are a landmark for those walking in the surrounding area. Located on a hill seven kilometers northwest of Arras, the two towers of Mont-Saint-Éloi are the monumental remains of an abbey with a thousand-year history.
Listed as a historical monument since 1921 and owned by the Pas-de-Calais Department since 2008, the two towers are the subject of a scientific and cultural project to raise awareness and promote their heritage. Between 2010 and 2015, the Department carried out restoration work, and its archaeology department conducted six excavations.

You absolutely have to see it. The climb is worth it ;-)
