Plessis-de-Roye Castle, locally known as Château de Plessis-de-Roye, lies in the village of the same name, in the Oise department in France. The castle and the village are sometimes also called Plessier-de-Roye but I could not find out why.
The castle is a Renaissance castle which is said to date back to the 15th century. Its appearrance reminds me somewhat of Blérancourt Castle, some 30 kilometers to the east.
I could not find any information at all about this castle other than that is was destroyed during heavy fighting in 1917 between French and German troops. If you know more, please let me know.
The castle seems to be private property and can not be visited.
