In 1910 during the restoration of Angerdshestra church 30 old pergaments were found revealing that the old church was inaugurated in the 13th century. Today documents are located in Stockholm Historical Museum. The current church was made of wood in 1669 to the site of medieval church. It was enlarged and restored in the 18th century. The oldest artefact is a wooden sculpture of St. Anne, dating from the 15th century. The altar was probably painted by Johan Kinnerus between 1716-1717.
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.
