The first evidence of Pyhtää as an independent parish dates back to 1380. At that time already the parish had a church, but it is not known where it was situated or what it looked like. Until 1600 Pyhtää included, besides its present area, also half of the present city of Kotka, Ruotsinpyhtää, Elimäki, the western parts of Anjalankoski, and a part of Lapinjärvi.
Dedicated to St. Henry, the church is situated where one of the westernmost branches of the river Kymi meets the ancient Turku-Viipuri coast road.
The building resembles the majority of the Finnish medieval stone churches. Pyhtää church, built about 1460, has retained its original medieval appearance almost untouched. There have been few alterations: the porch was converted into a memorial choir during the latter half of the 18th century, and in connection with repairs in 1907, buttresses were built to support the north wall and the sacristy was fitted with the outer entrance.
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.
