Fortress town Terezin lies north-west of Prague, at the confluence of Labe and Ohre rivers. The Fortress of Terezin was built between 1780-1790 to defend the route from Dresden to Prague, on the basis of experience gained during the period of Austro-Prussian wars in the reign of Maria Theresa Empress. As was the case with a second new, bastion fortress in Bohemia, Josefov in the north-east, it was built at the command of Emperor Joseph II. The plans by General Karl Clemens, Count Pellegrini, were realised as an ideal mode of the bastion type fortress.
