The artillery fortress is part of the border fortification line of 1936 till 1938. While visiting the fort you can see the underground space. There is an instructive trail around the fortress with information boards, explaining the fortification themes of the late thirties of the past century. In the entrance centre there is a permanent display of Czechoslovak pre-World War II army in miniatures from Lubor Šušlík collection. Fort "Jeřáb" is open for public on bank holidays only.
