You don't need to know that the Eiffel Tower in Paris is currently undergoing repairs etc. with the help of a huge elevator-like system build by a specialist firm from Limburg.
No, not Limburg in Benelux, but instead Limburg, the German town, which I know very well, because my father's parents lived there in a town approx. 20-30 km away from it.
If you want to see original medieval houses, Limburg is one of the towns to get to (among many others like Seligenstadt, for example, where Eginhard/Einhard, the biographer of Charlemagne The Great lived).
