The Styrian Armoury (Landeszeughaus) is the world's largest historic armoury and attracts visitors from all over the world. It holds approximately 32,000 pieces of weaponry, tools, suits of armour for battle and ones for parades.
Between the 15th century and the 18th century, Styria was on the front line of almost continuous conflict with the Ottoman Empire and with rebels in Hungary. In order to defend itself it needed troops and these troops needed equipment. The Styrian Armoury results from the resulting need to store large quantities of armour and weapons, and was built from 1642 - 1645 by a Tyrolean architect called Antonio Solar.
After about 100 years in use, Austrian empress Maria Theresia wanted to close down the armoury, as part of her centralisation of the defence of Austria. Nevertheless Styria petitioned for the ongoing existence of the armoury for both practical and sentimental reasons. Their petition was accepted and the Armoury was left intact, but largely decommissioned.
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.
