Královéhradecký kraj

The orginal fortress at Terezín was established in 1780 by Emperor Josef II to prevent the passage of enemy armies from the north.
It is comprised of three parts: the Lesser Fortress, the main fortress, and the fortified area between them. During the First World War, the Lesser Fortress served as a prison, and during the Second World War ill-fatedly for detention by the Prague gestapo.
