Rieneck Castle (German: Burg Rieneck) is a hill castle in the town of Rieneck, in Bavaria, southern Germany. It was built by Ludwig I, Count of Loon and Rieneck, around 1150. It is today used by the German Christian Guide and Scout Association. Rieneck Castle sits on a hill in the town of Rieneck, overlooking the Sinn River. It is located in the Spessart hills, in the Main-Spessart district of Bavaria, about 80 km east of Frankfurt.
In 1150, Ludwig I, Count of Loon and Rieneck, ordered the building of the castrum Rinecke on the northeastern boundary of his territory, intending to safeguard the lands of this aristocratic family against the neighboring lordships of Mainz, Würzburg, and Fulda. The little hill in the Sinn valley offered excellent conditions. There was only one direction where the castle required additional protection by a defensive ditch and offered as narrow a front as possible to attack. The latter can be clearly seen in the ground plan of the keep, the 19-meter-high “Thick Tower”, which is outwardly an irregular, seven-sided polygon, whose tip points towards the nearby hill. The castle complex initially consisted simply of a courtyard surrounded by defensive walls and the keep, with its 4 to 8-meter-thick walls. Inside the walls, half-timbered buildings were constructed as living quarters, store rooms, and stables. Of these, only what we now know as the “arched cellar” survives.
