Colditz Castle in the First World War

Hi everyone,

I was looking up references on Papers Past to Colditz, the castle that was used as a special POW camp during WWII, and I came across this article, mainly focused on Charles Upham VC*.

Within the article I noted this:
“…Colditz, south of Leipzig. In this ancient pile with its thick stone walls and dungeons, which had been used for prisoners during the last war…..”

Does anyone know, was Colditz Castle actually used as a prison for Allied POW’s in world War One? If yes, has anyone got any stories or history of the castle in that 1914-1918 period please?

Thanks.
