The Monastery of Philotheou is one of twenty monasteries on the Mount Athos peninsula and is located on the eastern side of the peninsula. It is twelfth in hierarchical rank among the monasteries. The name of 'Philotheou' is named after its founder, St Philotheos, and is derived from two Greek words which mean 'Beloved of God'. Philotheou functions as a coenobitic monastery.
Founded by St Philotheos in the last quarter of the 10th century, it was obscure until Serbian and Bulgarian monks settled there between the 14th and 16th centuries. As the Slav monks left, the monastery again became obscure; until the 18th century, when the Greek princes of Moldavia and Wallachia made grants to the monastery, with which the brotherhood had guest quarters, cells and chapels built.
In 1746, the central church was built, and over the next thirty years had fresco's painted, including the Mother of God Glykofiloussa and scenes from Revelation. Additionally, there are ten chapels connected to the monastery, four inside the monastery proper and six outside.
Philotheou possesses the wonderworking icon of the Mother of God Gerontissa, and it's library has 250 manuscript codices and two parchment rolls of the Divine Liturgy. The sacristy contains a piece of the True Cross and the right hand of St John Chrysostom, among other relics.

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.
