The current building of Pöide Church is believed to be built on the remains of a chapel built in 13th century. After the conquest of Saaremaa in 1227, the eastern part of Saaremaa belonged to the Livonian Order, who built a fortress at Pöide as their headquarters during the second half of the 13th century. This fortress was destroyed by the Saaremaa natives during the wave of uprisings against the occupying forces that took place in Estonia and Saaremaa during St.George's Night Uprising of 1343. There was a chapel on the southern side of the fortress, and the walls of this chapel form the central part of Pöide church. For its massive form, it is called fortress-church.
The building was looted and burnt during World War II and also used as a storage building. The building suffered severe damages in fire in 1940, when lightning struck the tower. The large crack in the tower from the lightning can still be seen today.Pöide church has been renovated and reconstructed slowly since 1989. Choir-part, stone-altar and vestry room have been renovated. Several big tombstones inside the church are exposed behind glass, showing the importance of the church as a cultural center for nearby communities during previous centuries.

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.
