The territory of the village of Berloz has been occupied since prehistoric times. Berloz was dominated by an important family who took the name of the village and whose castle was besieged several times during its history. Today, together with the church, the presbytery and the magnificent castral farm, it forms one of the most interesting architectural ensembles in our region.
The village of Corswarem was crossed to the north by the Bavay-Tongres Roman road. As for the Corswarem lineage, close to the Count of Looz, it had settled in a dungeon emmotté in the center of the village.
Rosoux-Crenwick is the result of an earlier merger, in 1822. The village of Rosoux lies in the north-western part of the commune of Berloz, while the hamlet of Crenwick, to the east of the commune, is separated from the other villages in the entity by several communication routes. Rosoux is aligned with the “Lange Beek”, a stream that flows through a series of sites of high biological interest. The hamlet of Crenwick, on the other hand, developed along a street and is made up of two large quadrilateral farmhouses and a few brick village houses.
