Fort Rapp is part of the 14 fortifications erected in Alsace by the Prussian general Von Moltke after the fall of Strasbourg in 1870 during the Franco-Prussian War and following the siege of Strasbourg. Built between 1872 and 1874 and inaugurated on 26 September 1874, it was part of the fortifications meant to protect the city from French attacks. Since 1918 and the return of Alsace-Lorraine to France, it is named after the French general Jean Rapp. The fort is located in Reichstett, a village situated 10 minutes north of Strasbourg and belonging to the Urban Community of Strasbourg. The fort contains 200 rooms and was able to host a garrison of 800 men. It was protected by 18 cannons of 90 – 150 mm.
References: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.
