The Regensburg Museum of History, currently resides in a former Minorite monastery, is a museum of the history, art and culture of Regensburg and eastern Bavaria from the Stone Age to the present day.
The former monastery of St Salvator, located in the city's Dachauplatz district, was founded in 1221 by the Bishop of Regensburg Konrad IV of Frontenhausen, Count Otto VIII of Bavaria, and King Henry VII. The three-naved basilica church was considered the largest church of the order in southern Germany until its closure in 1799.
The church and most of its monastic buildings survived, with the monastic buildings converted as barracks and billets for the Bavarian Army, and the church as a customs hall, a drill hall and a hotel until it became the location of the Regensburg Museum of History in 1931.
References:Château de Niort is a medieval castle in the French town of Niort. It consists of two square towers, linked by a 15th-century building and dominates the Sèvre Niortaise valley.
The two donjons are the only remaining part of the castle. The castle was started by Henry II Plantagenet in the 12th century and completed by Richard the Lionheart. It was defended by a rectangular curtain wall and was damaged during the Wars of Religion. In the 18th century, the castle served as a prison.
The present keeps were the central point of a massive fortress. The southern keep is 28m tall, reinforced with turrets. The northern tower is slightly shorter at 23m. Both are flanked with circular turrets at the corners as well as semicircular buttresses. Each of the towers has a spiral staircase serving the upper floors. The Romanesque architecture is of a high quality with the dressed stones closely jointed.
