The ruins of the Ramburg castle stand on the Schlossberg above the village of Ramberg in the Palatinate region. The river Dernbach, the left-hand headstream of the Eisbach) flows through the valley. Ramburg was built in the 12th century under the House of Hohenstaufen as an imperial castle for the protection of Trifels Castle. It is recorded as the seat of imperial ministeriales from 1163.
In 1519, Hans of Ramburg, the last member of the House of Ramburg, sold his castle to the Dalbergs. Six years later the castle was completely razed during the Peasants' War.
In 1540 the ruins were sold to the counts of Löwenstein. After being totally destroyed by a lightning strike in 1560 it was rebuilt as a residential castle again.
The castle was plundered during the Thirty Years' War, but not destroyed. Until 1638 it remained occupied as district office (Amtsitz), but fell into increasing disrepair and was used as a quarry in the early 18th century.
From the valley the impressive remains of the mighty shield wall and the palas are still visible. In addition, a neck ditch, several wall remains and a huge rock cellar have survived.
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.
