Metz’s main station may appear at first to be some sort of converted church, but in fact it’s an artefact of imperial – rather than religious – history. Despite being more than a century old, it’s the fourth railway station to occupy this site, and was built by Kaiser Wilhelm II to assert German sovereignty over the region in 1908. It incorporates a stained-glass window depicting the Holy Roman Emperor Charlemagne, as well as private apartments for the Kaiser (now the headquarters of French state-owned rail firm SNCF).
