📍 Mondorf-les-Bains Center Finally (or as a prelude), the trail leads through the expansive Parc Thermal – with shady avenues, manicured flowerbeds, babbling fountains, and elegant spa architecture. A place that combines exercise and relaxation, ideal for taking a breather or lingering. 💡 Tip: Be sure to slow down a bit – the park invites you to see, feel, and enjoy. If you like, sit on a bench and watch the day pass by.

The chapel near the source of the Syre is dedicated to Saint Donatus, the patron saint against lightning and fire. During its restoration in 1965, excavations were carried out in the surrounding area and clay bricks and pottery from the Roman period were discovered. The chapel's highly symbolic location, near the source and at the foot of the hill, suggests that it has been a sacred site since pre-Christian times. The mythical character of the place is reinforced by the presence of the imposing 500-year-old oak tree, which dominates the chapel. This remarkable tree is 15 m tall and has a diameter of 162 cm at breast height.
