R. I. P. Mystery Cache

When the Luxembourgish Government decided in the 1950s to build the Upper Sûre dam, an area of 3’800’000 m2 was inundated, including a village, some mills and bridges.

During the last emptying for maintenance in 1991, many other unusual things, which were buried for years under a huge volume of water, were found.

Who knows, what else is still lying undiscovered in the mud …

If you want to sign the book of condolence, you have to answer the following question :
