Lamphey Bishop's Palace is a ruined medieval building complex in Lamphey. Whilst early thirteenth-century fragments from the old hall still exist, the palace, including the 25 metres great hall, was largely constructed under Bishop Henry de Gower, Bishop of St David's (1328–1347) and was used by high-ranking clergy. The palace was built in three stages and originally had over 20 rooms and featured fishponds, orchards, fruit and herb gardens and areas of parkland with grazing deer.
The palace was surrendered to the crown in 1546 during the reign Henry VIII and granted to Richard Devereux and subsequently the Earls of Essex. Walter Devereux, 1st Earl of Essex lived in the palace as a child. The palace was sold to the Owens of Orielton in 1683, possibly due to damage in the English Civil War. The buildings were possibly used for farm purposes in this era.

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.
