Colditz — Germany
The 2005 ITV series dramatises life inside Oflag IV-C at Colditz Castle — the supposedly escape-proof castle where the Reich's most determined Allied escape artists were concentrated.
Colditz Castle in Saxony served as Oflag IV-C from 1940 to 1945, holding British, French, Dutch, Polish and other Allied officers deemed troublesome escape risks. Despite being Germany's most heavily guarded POW camp, more than 30 successful escapes were made — the highest ratio of any camp in Germany. The 'Colditz Glider', built secretly inside the castle, was never used as the war ended first.
