Leicester's Church, originally known as St David's Church, is a large ruined church near to the hill top castle at Denbigh, North Wales. It was built for Robert Dudley, 1st Earl of Leicester, from 1578, but financial difficulties meant work stopped in 1584. When the Earl died unexpectedly in 1588 the project was abandoned. It had been the only large church-building project in Elizabethan England or Wales. On Robert Dudley's death with no heir, his estates reverted to the Crown, as a roofless enclosed space. It is now a Grade I listed building and Scheduled Ancient Monument, cared for by Cadw, the Welsh historic environment service.

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.
