The history of Inju manor (Innis) goes back to at least 1520. In 1894 the current building was erected, probably designed by architect Rudolf von Engelhardt. It is one of the most characteristic examples of neo-Renaissance manor house architecture in Estonia. Starting in 1920, the manor house accommodates a orphanage.References:
Prunn Castle is perched on an almost vertical Jurassic outcrop high above the Altmühl river valley south-west of Regensburg. Its impressive appearance from a distance is matched by the views from the castle of the surrounding Altmühltal countryside.
Lords of Prunn were first mentioned in 1037, and they will have certainly chosen the site because of its favourable position on several transportation routes. The castle itself dates from around 1200, a time when many castles were being built. The Danube region centring around Kelheim became very important in this period under the Bavarian duke Ludwig I. One of the oldest parts of the castle is the 31-metre keep.
In 1288, Duke Ludwig of Bavaria acquired the castle from the lords of Prunn-Laaber. In the first half of the 14th century the duke then invested the Fraunberg vom Haag family with the castle.
