The story
The village was first mentioned in 1333 as "Vetus Turnoltum". Oud (old) has been added to distinguish from the village which developed around the castle which was built in 1109 or 1110. That village would eventually become the city of Turnhout. Oud-Turnhout used to be part of the municipality of Turnhout, but felt neglected by its bigger neighbour. In 1859, Oud-Turnhout became an independent municipality. In 1977, the hamlets of Schoonbroek en Kinschot became part of Retie, the area Kijkverdriet was awarded to Ravels, and the remainder became part of Ravels.
