The St. Mary's Church is a medieval stone church located in Maaria. There are no records as to when the present church was built, but the work was probably started in the mid or late 15th century. According to Markus Hiekkanen, the church was probably built in the 1440s. On the basis of the style of the closets, the gables were constructed about 50 years later.
There are medieval limestone paintings on the walls, which are not common to other places in Finland. The most valuable artefacts are the wooden alter cabinet and large altarpiece depicting Christ on the cross.
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.
