The beautiful spa town of Mondorf-les-Bains has a long history. Originally an outpost of Roman fortifications, the town was later given its name by one of Charlemagne's nieces. Over the following centuries, Mondorf found itself under attack due to its position next to the French border, and during the Middle Ages much of its centre was rebuilt on a few separate occasions.
The town's fortunes changed forever in the 1840s. Karl Gotthelf Kind was drilling underground in the hope of finding salt, which was being heavily taxed by the Dutch at this time. Instead he found spa waters, which were soon developed and opened in 1847. The spa's healing properties were soon being celebrated, and a stream of Europe's wealthiest tourists was regularly visiting the town. A number of Mondorf's beautiful buildings date from this period. Today the spa continues to be a great success, thanks to its rich mineral waters and beautiful surroundings in the charming town's park.
