St. Lambrecht's Abbey was founded in 1076 by Count Markward of Eppenstein; it was dissolved from 1786 to 1805. In 1938, the building was seized by the National Socialists. From 1942 to 1945, it was used as an external storage facility of the Mauthausen-Gusen concentration camp. The monks returned in 1946.
Locally the two churches within the monastic grounds are called the Grosskirche ('big church') and the Kleinkirche ('little church'). During restoration work of the Grosskirche in the early 1970s extraordinary frescoes dating from the latter half of the 15th century were discovered on the north wall. These show the throne of Solomon.
On the lowest level is depicted the Old Testament Judgment of Solomon, above this the Virgin Mary with the baby Jesus, and above all else Jesus Christ: 'the Word of God made Flesh'. Other frescoes dating from the 14th century depict Saint Christopher and Saint Agnes. Formerly in the monastery there was also a votive altarpiece from which the Master of the Saint Lambrecht Votive Altarpiece received his name; this is now in the Alte Galerie in Graz.
References:The Clementinum is a historic complex of buildings in Prague. 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.
