La Roche is believed to have first been settled in the
Neolithic era. There is a Celtic archaeological site dating between 850 and 520 BC. The
Romans built a fort there following their conquest of Gaul and the Ardennes. The
town's medieval castle was in use between the 9th and 18th centuries. It provided protection to the many barges that plied their trade along the local river systems. It may have been the site of a
sporting lodge of
Pippin, and certainly the counts of La Roche held it in
fief from his descendants, the
Carolingian rulers. In the 12th century they sold it to the
counts of Luxembourg. In 1976 there was a merger of administrative districts in the area that resulted in the municipality of La Roche-en-Ardennes.
Beausaint,
Halleux,
Hives,
Ortho and
Samrée were joined by
Cielle detached from
Marcourt, now within the municipality of
Rendeux. ==Economy==
