Malla manor traces its history back to 1443, when it is first recorder in written sources. During that time, there was a small castle at the site. Around 1620, the estate became the property of Swedish field marshal Gustav Horn. In 1651-1654, he commissioned architect Zakarias Hoffmann to erect a new manor house on the site. The house burnt down during the Great Northern War, and the current building received its appearance in the 1880's. The estate is now privately owned.
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.
