Penallt Old Church dates from the late thirteenth century or early fourteenth century and its dedication is unknown. The main part of the building is medieval, although the base of the tower is earlier, and the porch is later, bearing a date of 1539. The church was restored in 1885-7 and again in 1951. It is constructed of Old Red Sandstone.
The interior has a barrel-shaped ceiling from the sixteenth century and a four-bay Perpendicular arcade. It also contains an elaborate coat of arms of Queen Anne, dating from 1707. The altar table was carved in 1916 by a war refugee from Belgium, who was reputed to be a master carver at St. Rumbold's Cathedral in Mechelen.

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.
