One of the oldest monuments of Luxembourg can be found on the ''Béisenerbierg''. The menhir, buried for centuries in the ground of a meadow, was discovered in 1978 and erected 30 metres away from its original location. The 3 metres high sandstone, weighing around 4 tons, owes its brown yellow colour to its high iron content.

On the site 'Mies', a Roman villa was excavated which was of impressive size; 200 x 600 m. The visitors can discover the well preserved central heating system (hypocaust - which is roofed) and the water basin ( 75 x 6.5 m) which was located in front of the villa.

A diving tower, a water slide, indoor and outdoor water games promise entertainment for the entire family. Outdoors you can play a game of beach volleyball, or just relax in the sun. The sports area gives you the opportunity to burn off some extra energy. If you are rather looking for relaxation, the wellness area on the first floor is the place to be.
