Here are some links to websites for general information on the history of workhouses and the military occupation of Albro during the Second World War. The above image was taken during WWII.

 

Andrea Sutcliff produced this website after visiting Albro and seeing the names of her father's two best friends written on the wall in Plas-Y-Berllan.
