Colditz Castle is a Renaissance castle in the town of Colditz near Leipzig, Dresden and Chemnitz in the state of Saxony in Germany. It gained international fame as Oflag IV-C, a prisoner-of-war camp during World War II for "incorrigible" Allied officers who had repeatedly escaped from other camps.
The castle lies between the towns of Hartha and Grimma on a hill spur over the Zwickauer Mulde. It had the first wildlife park in Germany when, in 1523, the castle park was turned into one of the largest zoos in Europe.
