The Church of Saint Demetrius of Thessaloniki in Veliko Tarnovo, Bulgaria, a medieval Bulgarian Orthodox church, was part of a monastery and played a role in the anti-Byzantine Uprising of Asen and Peter in 1185. Destroyed in the 13th century, it was reconstructed in the 1350s. Plundered in the 18th and 19th centuries, it was completely destroyed by an earthquake in 1913, leaving only the apse and fragments of frescoes. Reconstruction began in 1977–1985, led by Teofil Teofilov, based on architectural remains and examples from better-preserved Bulgarian churches. Two layers of frescoes, dating to the church's construction and the 14th century, have been preserved.

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.
