The St. Mary's Church in Sønderborg is located on a hill and is a very iconic for the city. In the Middle Ages there was a leper colony on a hill just outside the city. It was named after Saint George and around 1300 the chapel of this leper colony stood in the place of the present St. Mary's Church. After the old parish church of the city, the St. Nicholas Church, was demolished around 1530, the Saint-George chapel became the new main church. Towards the end of the 16th century, John II, Duke of Schleswig-Holstein-Sonderburg commissioned the enlargement of the building in order to make it suitable for the function of the parish church of his city.
In 1595 a start was made on the partial demolition of the old church and the construction of the new church. Only parts of the old medieval church remained. From the medieval church, a medieval wooden wall cupboard dating from about 1400 remained. The solemn inauguration of the new parish church took place just before Christmas in 1600. In 1649 the George Church was renamed as the Mary Church.

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.
