@efs.tujfi: Luxembourg City: The Fortress Hidden Beneath a Beautiful Old Town Luxembourg City looks like a peaceful European city surrounded by rivers, greenery, and beautiful historic streets. But beneath this picturesque landscape lies a very different past. Once known as the “Gibraltar of the North,” Luxembourg was one of Europe’s great fortified cities. Deep beneath the old town, enormous casemates and defensive tunnels were carved into the rock. Today, much of the fortress has disappeared, but its remains still reveal the fascinating military history hidden beneath this beautiful city.
