St Daniel's Church is situated on a hill approximately 1.1 kilometres south of Pembroke Castle. One of the oldest churches in the area, it is located on an ancient, pre-Norman site associated with Saint Deiniol throughout the 6th century.
The saint to whom it is dedicated is Deiniol, who according to tradition was the first Bishop of Bangor. It is claimed that Deiniol had a hermit's cell on the site, pre-dating the church, and the site has also been linked to Saint David. The site gained a reputation for miraculous healing, and became a shrine for pilgrims who would drink from the well.
The current structure dates to the 14th or 15th century. It underwent repair in 1780, and again in 1849 and 1893. Today, the church, a small structure built of rubble stone with a slate roof, is disused. It has a nave, a chancel, and a spire, with a tower on the western side.
By 1832 the building was in private hands and it was being bought and sold along with the land on which it was built. At the end of the 19th century it was in use only as a cemetery chapel.

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.
