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 Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
