Petäjävesi old church was inscribed on the UNESCO World Heritage List in 1994. It was designed and built in 1763-64 by a local peasant master-builder, and in 1821 his grandson added the bell tower at the west end. Petäjävesi was then part of the Jämsä congregation, but the trip to Jämsä church was too long for local people. The Crown of Sweden had accepted the request to build a graveyard and a small village church at their own expense as early as in 1728, but building was delayed nearly forty years. The church was located to a typical old countryside site. It was chosen so that the parishioners got easily there by boat or in the winter stay over.
When the newer church was completed in 1879, old church was abandoded for nearly for decades. The period of neglect between 1879 and the 1920s was a blessing in disguise. The historical importance of the church was noticed first by the Austrian art historian Josef Strzygowski in the 1920s. After 1929 church is renovated several times.
Petäjävesi olf church is a very unique and well-preserved wooden church representing the wooden architecture tradition of eastern Scandinavia. Nowadays it’s a popular tourist attraction and open every day in summer time (in winter season by appointment).
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.
