The Eastern Orthodox Keras Kardiotissas is dedicated to Virgin Mary that is situated near the village of Kera of the Heraklion regional unit in Crete. It is built on the north slopes of Mt. Dikti, at an altitude of 650 m and a location that is approximately 50 km east of Heraklion, next to the road to Lasithi Plateau.
The exact date of the monastery's establishment is unknown. However, references to it are made in manuscripts dating from the early fourteenth century. The monastery was named after an old icon of Theotokos that according to tradition was miraculous. That icon was stolen in 1498 by a wine merchant and transferred to Rome where it is now permanently enshrined in the Church of St. Alphonsus near the Esquiline Hill. The stolen icon was replaced by another one in 1735 that is also regarded as miraculous. During the Ottoman occupation of Crete, the monastery often served as a local revolutionary center and suffered several retaliatory attacks as a result. In 1720, Kera monastery became Stauropegic (independent of the local Bishop).
The monastery is surrounded by fortified walls. The main church (katholikon) was originally built as an arch-covered single space structure and was later expanded with two narthexes and a smaller chapel. The church features murals dating to the 14th and 15th centuries.
Today, the monastery functions as a nunnery. It celebrates the birth of Mary on September 8th every year.

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.
