Lydstep Palace is a ruinous medieval hall house. Believed to have been built in the late 14th century or 15th century, the building was constructed from limestone and built in two levels, the upper floor containing a hall and the lower floor consisting of several barrel vaulted rooms, likely cellars. The two floors were not connected internally, only by external stone stairs. Speculation as to the purpose of the house varies, some sources attribute the building as a court of the Manor of Manorbier and Penally, but it has also been referred to as a hunting lodge of the Bishop Gower of St. Davids.
The house was traditionally known as the Place of Arms, and it is speculated that this became mutated to the Palace of Arms, leading to its current name of the Palace. The building is also referred to as The Old Palace.
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.
