Medical experiments were conducted at Dachau with Jews helplessly used in decompression and high altitude tests. Others were infected with malaria to test possible vaccines.13 In the twelve years Dachau was operational, more than 200,000 prisoners passed through the camp.13 Officially more than 30,000 died at Dachau but the actual number is thought to be much higher.13
In town there are still parts of the Schleißheimer canal remaining today. This canal was built in the mid-eighteenth century as part of the northern Munich canal system to which the Nymphenburger Canal belongs as well. It functioned as a transportation route between Dachau and Schleißheim. The building material recovered from the demolition of three wings of the Dachau castle was transported to Schleißheim this way.
The camp was liberated on April 15, 1945, by the British 11th Armoured Division. The soldiers discovered approximately 60,000 prisoners inside, most of them half-starved and seriously ill, and another 13,000 corpses, including those of Anne and Margot Frank, lying around the camp unburied. The horrors of the camp, documented on film and in pictures, made the name "Belsen" emblematic of Nazi crimes in general for public opinion in many countries in the immediate post-1945 period. Today, there is a memorial with an exhibition hall at the site.
