La Gleize is located on a rocky outcrop overlooking the valley of Amblève in the Ardennes region.

This is due to the work of a native of the town, Louis Remacle, professor at the University of Liège and member of the Royal Academy of French Language and Literature of Belgium, who based part of his research there.

A Romanesque building of the 12th century, built in local stone, contains the red marble tomb of the Lords of Froidcourt.

It was virtually rebuilt between 1945 and 1951: a photographic panel presents views from inside the church before the serious damage caused in 1944 by the Battle of the Bulge.

A German Tiger II tank is at the entrance of the building, inside is an abandoned reconnaissance armored Willys Jeep in perfect condition.
