The tower and northern wall are the oldest parts of Aspö Church (dating from the 12th century). The chancel was completed in 1300s and the church was enlarged in 1400s. It has an interesting inventory; the fine iron-made door between nave and porch dates from the original church, font is from 1200s and the large altar triptych from 1472. There is also a runestone from the 1000s in the church porch.
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.
