Fairly near our town is an old WW2 Prisoner of War camp, commonly known as Island Farm. During the War, it housed many German prisoners, including many of high rank.
There was a famous escape via a tunnel dug by the prisoners, and it is such a shame that the local council, in its infinite wisdom (hollow laugh) decided to demolish all the camp except for one hut, padlocked shut in a neglected field. Plans are afoot to build a sports centre on the majority of the historic site......
There are some excellent web sites, which I have atttempted to collate in one place:
Some famous prisoners
The main site
An excellent and very comprehensive site
