Schadeck Castle is the most recent and smallest, but still most interesting of the four Neckarstein castles. It is perched on the high mountain like a bird's nest, which is why it is, in fact, called the 'Swallow's Nest'. After Ulrich II (1236-1257) inherited the 'front castle' from his father Ulrich I and another son joined the clergy, Bligger V, the third son, was forced to build a new castle. However, there was no more room on the mountain ridge where the other castles stood and thus he had to erect it downstream from the front castle on the slopes of the rocky massif that drop steeply to the Neckar River. This location must have caused enormous difficulties during the construction. To save the level ground for the castle complex and provide it with a frontal ditch as protection against the mountainside, a large chunk of the steep rock face had to be hewn out.
The castle itself stands on a rocky basement and appears to literally grow out of the mountain. Along the top of the high curtain wall, the most likely place to be attacked, runs a covered wall-walk with little towers on both sides. They command a panoramic view of the Neckar River valley and the impressive walled town of Dilsberg. Visitors to the castle today walk along a path from Neckarsteinach, which leads through the former frontal ditch. Earlier access was by way of a steep serpentine path from the Neckar. Today the ruin is the property of the state of Hesse and was recently restored at great cost. It can be viewed at any time free of charge and the curtain wall can be climbed.
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.
