The Korppoo Church was erected probably between years 1430 and 1440. It represents the oldest church architecture in Finland. Good example of this is the stone tower, which was probably built for defensive purposes, not for belfry. When the church was renovated in 1952-1953, several overpainted medieval wall paintings were found overpainted and restored.
The oldest wooden statue in Finland, "Korppoon madonna", was originally in the Korppoo Church. It was made in Rheinland approximately in 1225. Today the statue is preserved in National Museum of Finland (Helsinki).
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.
