The imposing red brick church in Keldby is one of the three Møn island churches decorated with frescos by the Elmelunde Master, probably towards the end of the 15th century. In the so-called Biblia pauperum style, they present many of the most popular stories from the Old and New Testaments. There are also a number of earlier frescoes in the church dating back to about 1275.
The original nave and choir were constructed in the first half of the 13th century. Around 1480, the nave was expanded with cross vaults and the choir was heightened with limestone. The tower was added in the 16th century and a small sacristy was built about 1700. The richly carved altar triptych and the pulpit are from 1586.
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.
