Erected in 1905, the Château de Mercy was built in response to the architectural shift in the region under German occupation. It is thus possible to admire its clearly French style.
There is a very nice combined pedestrian/bicycle path around the lake (Promenade Symphonie). He can be committed very well and you have beautiful views of the lake.
The castle dates from 1720 and was the residence of the Marquis de Pange. It is still family-owned today and unfortunately (currently) not open to the public.
