The exact age of the original St. Mary's Church (Marienkirche) site and structure is not precisely known, but it was first mentioned in German chronicles in 1292. It is presumed to date from earlier in the 13th century. The architecture of the building is now largely composed of comparatively modern restoration work which took place in the late 19th century and in the post-war period. The church was originally a Roman Catholic church, but has been a Lutheran Protestant church since the Protestant Reformation.
Along with the Nikolaikirche, the Marienkirche is the oldest church in Berlin. The oldest parts of the church are made from granite, but most of it is built of brick, giving it its characteristic bright red appearance. This was deliberately copied in the construction of the nearby Berlin City Hall, the Rotes Rathaus. During World War II, it was heavily damaged by Allied bombs. After the war the church was in East Berlin, and in the 1950s it was restored by the East German authorities.
Before World War II, the Marienkirche was in the middle of a densely populated part of the district of Mitte, and was in regular use as a parish church. After the war, this area was cleared of ruined buildings and today the church stands in the open spaces around the Alexanderplatz, and is overshadowed by the East Berlin television tower, the Fernsehturm.
There is a striking statue of Martin Luther outside the church. The Marienkirche also contains the tomb of Field Marshal Otto Christoph von Sparr. Carl Hildebrand Freiherr von Canstein, the founder of the oldest Bible society of the world, the Cansteinsche Bibelanstalt, was buried here in 1719.
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.
