Panagia Apsinthiotissa or Absinthiotissa is a Greek Orthodox monastery probably established in the 11h or 12th century as a Byzantine imperial foundation and continued to enjoy a degree of prominence in the Lusignan and Venetian periods. Leontios, the abbot in about 1222, was one of the delegates sent to report the plight of the Orthodox Church under Latin jurisdiction to the Patriarch Germanos II in the Empire of Nicaea. Neophytus, Archbishop of Cyprus, was also in Nicaea at the time, having been banished by the Latin authorities for refusing to take an oath of obedience to the Roman Pontiff. Boustronios tells us that the Queen of Cyprus worshipped at the monastery in 1486, the implication being that Panagia Apsinthiotissa was under the Roman Church. He also reports that pilgrimages were made to Apinthi and Antiphonitis on the fifteenth of August by all the people of Kyrenia. After the Ottoman conquest, the monastery became the property of the Orthodox Patriarch of Jerusalem and subordinate to the nearby Monastery of Saint Chrysostom in Koutsoventis.
The main church of the monastery appears to have been built in the 12th century and has a cross-in-square plan of the Byzantine type surmounted by a high dome. The narthex, on the west side, has simple Gothic rib vaulting and probably dates to the 15th century. Writing in 1918, George Jeffery describes the establishment as a ruin.

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.
