Luxembourg street... - Luxembourg, Luxembourg. BTW: The motto of Luxembourg is inscribed on the small 'demi-turret' protruding from the façade: Mir wolle beiwe waat mir sin! (We wish to remain what we are!)
Mine St Michel, Luxembourg. This waterfall is one of several in the Spring Room of the Marvel Cave, sitting some 500ft underground. The caves system was originally called Marble Cave, as early explorers believed that they could see marble on the cave’s roof – though they were eventually proved wrong.
