Højby Church dates back to the beginning of the 12th century and it is constructed in granite. Several modifications have taken place since the original construction including a porch in the 13th century, Gothic cross-vaulting in the nave and chancel in the 14th century, a tower around the year 1400 as well as a vestry, a chapel and a new entrance porch towards the end of the Middle Ages.
The church is recognised for its fine wall paintings which are considered to be among the best in the country from the late Gothic period. They were probably created at the beginning of the 15th century, shortly after the cross vaults were added. They were discovered in 1901 and have been restored on several occasions. During the last restoration in 2007, the painting of Erasmus' martyrdom was revealed for the first time.
The paintings in the chancel tell the story of the Day of Judgment with images of Christ, a basoon-playing archangel and St Michael. The lost souls are shown going to hell with the devil standing in its flames. There is also a painting of St George and the dragon including the Syrian princess he saved from the dragon.
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.
