One of the loveliest castles in the area, Warfusée was completed in 1754 as a replacement for an earlier Renaissance structure.

To this day it still is the main residence of the Earls of d'Outremont. Access to the yard is via a gate under a tower with a steeple. The main building is flanked by two lower wings marking the boundaries of a vast yard. The rich interior has remained pretty much as it was at the time of building. The interior is truly exceptional; many talented artists were called upon: stuccos in the chapel, the superb entrance hall paved with marble with its beautiful staircase, the various drawing rooms with tapestry, the dining room with walls decorated with hand-painted engravings, and the huge library. The house is open to the public upon request for groups only.

The Schmerling Caves (also known as Grottes d'Engis, meaning Engis Caves) are a group of caves located in Wallonia on the right bank of the stream called the Awirs, near the village of Awirs in Flémalle, Belgium.

They were explored in 1829 by Philippe-Charles Schmerling, who discovered, in the lower cave, the remains of two individuals, one of which, now known as Engis 2, was a fossil of the first Neanderthal ever found; the other was a Neolithic homo sapiens.

The caves have been classified on the list of Cultural Heritage of Wallonia sites since 1978, as well as Exceptional Cultural Heritage of Wallonia since 2013, because of the Neanderthal fossil.
