The St.Caherine's Church of Muhu is considered one of the most remarkable early-Gothic buildings in Estonia. It was first mentioned in Hermann von Wartberge's Chronicle dated 1276. The exterior architecture of the Muhu Church is a strict monumental style and its originality is prominent. The Muhu Church has preserved its original shape. Around 1663, a little wooden steeple was added to the church, but perished together with the roof in 1941. In 1993, during the restoration period an additional roof was constructed on the facade of the church to protect the church bell.
As for the interior furnishings of the Muhu Church one will find an altar table made of dolomite, which has been preserved from the time of its original construction. Also the stone base of the baptismal basin originates from the Middle Ages.
The pulpit is in Renaissance style and was completed on 1627. It is one of the oldest in Saaremaa and was made by Balthasar Raschky. The Classicist altar was created by Nommen Lorentzen in 1827. The altar painting has survived from the original altar and the painting was finished in 1788.
In the Muhu Church and churchyard there are worth noting the trapezium-shaped tombstones with pagan symbols found only on the islands and Western Estonia. They have been traced to the 12th and 13th centuries. The most intricate tombstone is presently located in the frame of the door leading to the wall staircase. It is one of the two preserved in Estonia from the 12th-13-th centuries depicting human figures. Through discovering tombstones, bones and some other rare archaelogical finds, the church is thought to have been erected on a sacred site of the ancient Muhu inhabitants.
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.
