Saint Wenceslas Cathedral is a neo-gothic cathedral in Olomouc. The square was named after Saint Wenceslaus I, Duke of Bohemia on the thousandth anniversary of his death in 1935. The cathedral is also named after him.
The cathedral began in the Romanesque style and was consecrated in 1131. Extensive Gothic modifications were made in 13th and 14th century. Czech king Wenceslaus III of Bohemia was murdered in a nearby house of the former dean of the cathedral on August 4, 1306. Wenceslaus III was the last of the male Přemyslid rulers of Bohemia.
Gothic revival changes, which included refacing the building, rebuilding the west front and the construction of the central tower, were made during 1883–1892. These were designed by Gustav Meretta and R. Völkel. The cathedral's main tower is 100,65 metres high, making it the 4th tallest building in the Czech Republic.
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.
