The village officially changed its name from Petegem into Petegem-aan-de-Schelde in order to distinguish itself from Petegem-aan-de-Leie.

[2] During the Early Middle Ages, a castle which became later known Old Castle of Petegem [nl], was located in Petegem on the left bank of the River Scheldt.

Most of the castle was destroyed during warfare, and by the 17th century only a ruin remained.

[4] In 1847, Baron August Pycke de Peteghem commissioned the construction of the New Castle of Petegem [nl] near the location of the old castle.

The castle and lands are nowadays owned by the Golf- and Countryclub Oudenaarde.
