Terezin is located approximately ninety miles north of Prague and just south of Litomerice. The town was built in 1780 by Emperor Joseph II of Austria and named after his mother, Empress Maria Theresa. Terezin consisted of two fortresses. The Big Fortress was surrounded by ramparts and contained a barracks. However, Terezin had not been used as a fortress since 1882 and had become a garrison town, which was almost entirely separated from the rest of the countryside. Terezin changed dramatically when the Nazis renamed it Theresienstadt and sent the first Jewish transports there in November 1941. These workers made up the Aufbaukommando (construction detail), later known in the camp as AK1 and AK2. These men were sent to transform the garrison town into a camp. These workers transformed the town, that in 1940 held approximately 7,000 residents, into a concentration camp which held about 35,000 to 60,000 people.
