The Porte Aïve Cave

The Porte Aïve Cave (which means "high door") is located on the left bank of the Lisbelle stream, a tributary of the Ourthe and is of great archaeological (and geological) interest. Archaeological digs were carried out in the cave in 1907-1908, as well as in 1956. During the first digs, that mainly focused on the porch and terrace, a sepulture from the neolithic was discovered (9,900 to 3,300 B.C). Interesting fact: in late 1944, the Germans had set up a command post in the cave.
