Ebelsberg Castle is located in the south of Linz. Due to its elevated position on the Schiltenberg, the castle can be seen from far above the city. The quadrangular, two-storey complex around a trapezoidal inner courtyard with its now smooth fronts no longer gives much indication of the former late medieval luxury of the Passau bishop's seat.
Ebelsberg Castle gained military-historical significance during the Napoleonic Wars. Napoleon himself had pointed out the strategic location of Ebelsberg. In the course of the 'Battle of Ebelsberg' on May 3, 1809, a fierce battle developed around the castle, which, like the market, went up in flames.
The battle of Ebelsberg is depicted in three dioramas. The Military History Collection in the Ebelsberg Castle provides a survey of the development of small firearms and handguns from the 18th century to the present. The collection focuses on the weapons and arming of the armies at war in World War I. There is also an extensive and informative exhibition of items from the navy of the Austro-Hungarian Empire including numerous model ships recalling this era.
The Chapel of St. Martin is the only completely preserved Romanesque building in Vyšehrad and one of the oldest in Prague. In was built around 1100 in the eastern part of the fortified outer ward. Between 1100 and 1300, the Rotrunda was surrounded by a cemetery. The building survived the Hussite Wars and was used as the municipal prison of the Town of the Vyšehrad Hill.
During the Thirty Years’ War, it was used as gunpowder storage, from 1700 to 1750, it was renovated and reconsecrated. In 1784, the chapel was closed passed to the military management which kept using it as a warehouseand a cannon-amunition manufacturing facility. In 1841, it was meant to be demolished to give way to the construction of a new road through Vyšehrad. Eventually, only the original western entrance was walled up and replaced with a new one in the sountren side. The dilapidating Rotunda subsequently served as a shelter for the poor.
