Neuscharfeneck castle ruins are situated in the eastern part of the Palatine Forest. They lie on the western foothills of the Kalkofen Berg in the middle of a forest and are only accessible over forest tracks.
The first castle, dating to the 13th century, was considerably smaller than the present ruins. Of the Hochstaufen castle only a few remnants have survived.
The entire site measures about 60 by 150 metres. Its shield wall, built from ca. 1212 to 1232 and extended in the years 1470 and 1530, is the mightiest in the Palatinate, with a length of 58 metres and thickness of 12 metres. Within the shield wall there are relatively few usable passages, chambers and casemates. It therefore acted - apart from the hoarding (Plattform) that has not survived - primarily as passive protection for the castle behind it. The original entrance was over a drawbridge through the shield wall into the castle.
In the castle gardens, rare herbs such as White Henbane, Ingräu and Abbey Hysop were planted.
There is still a partially surviving gateway with a flanking tower. Four water basins, chiselled out of the rock in the 13th century, were used as cisterns, that were supplied with rainwater and, from the 16th century, with water from the Roßberg Spring, 2 kilometres away, over pipes made of clay or hollow tree trunks.
The 30-metre long upper castle (Oberburg) on the central rock was built from 1212 to 1232 as the first residential building but has unfortunately not survived, apart from its well and an inaccessible chamber and steps in the rock.
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.
