According to various sources, the Rieterschloss (Im Schlosshof 2) is said to have been built for the first time in 1288 by the son of Konrad von Kornburg, or even before 1236 if one takes into account the deed of donation to Konrad von Kornburg, who named himself after this castle. The buildings, which are almost ring-shaped by a moat (in the Middle Ages, or before the construction of the modern sewer system, the moat was still filled with water due to the high groundwater level) enclose a rectangular inner courtyard. The tower protected the entrance with the drawbridge on the south side. There is a farm yard in front of the castle gates. The messengers, fowlers, gardeners and day laborers lived in the east wing of the completely rebuilt farmyard south of the castle. The coach houses and stables were formerly housed in the west wing. In the adjoining castle garden there was a rich tree population, a summer house and the castle courtyard. The entire complex opened towards the village through the outer gate, the Vallettor (Vallet = farewell). Wikipedia
