The Leonrod water castle was built in the 13th century as the family seat and Ganerbenburg of the lords of Leonrod, who were descended from the lords of Buttendorf, in order to protect an important road link to the city of Nuremberg. The castle was first mentioned in 1235 with a Rudolf miles de Lewenrode.
In the 14th and 16th centuries structural changes were made to the castle. The castle survived the Thirty Years' War unscathed, but shortly afterwards, in 1651, it burned down as a result of negligence - attempts to burn off vegetation in the moat got out of hand - and it was never rebuilt. In the 17th and 18th century a hunting lodge was built. The castle is owned today by a community of heirs that go back to the aristocratic line that died out in 1951.
One of the members of the nobile family was Franz Leopold, Baron of Leonrod, who was Bishop of Eichstätt from 1867 to 1905 and is one of the most important bishops of this diocese.
This castle is surrounded by a deep moat. It has four buildings around a rectangular 20-metre-high bergfried with an elevated entrance, 9 metres above ground level. The bergfried has a ground plan 6 x 6 metres in area and a wall thickness of about 2 metres. In the outer ward is the castle chapel, St. George's, which dates to 1327, and the hunting lodge with its hipped roof and timber-framed upper storey. Today, the castle still has the almost fully preserved bergfried, considerable wall remains, vaults, the castle well in the courtyard and an outlying tower.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
