Luxembourg

By Travelog Editorial Team · Updated August 8, 2026

Luxembourg is live on Travelog with one city, Luxembourg City, whose Old Quarters and Fortifications were inscribed by UNESCO in 1994, recognized for a fortified history stretching from the 16th century until the walls were dismantled in 1867. The Bock Casemates, part of a 23-kilometer underground tunnel system carved into the rock, remain open to visitors today.

Luxembourg City's documented defensive history, a fortress considered one of Europe's greatest from the 16th century until its walls came down in 1867, is worth understanding directly through the Bock Casemates, a genuine, still-explorable piece of that 23-kilometer tunnel network. Its landmark page is live now.
