Keila Church is the biggest medieval country church in Harju county, which was obviously established shortly after the North Estonia was occupied by Danes. In 1280 a spacious square chapel was established at "Keila hill", where today there is the chancel of the church. Fragments of the paintings at the chancel walls date possibly from this period already. The main body of the church remained unbuilt at the beginning and was obviously established at the first half of the 14th century. As the influence of the Dominican order, the main body of the church was simple unvaulted box-like building.
The church was expanded in the 15th century. First the massive west-tower was built. Three-sided ending was added to the chancel, it was re-vaulted and altar table of stone was made. In 1480 southern portal was established. In 1489 the church was vaulted and it became two-aisled, which is rather seldom in Estonian churches. The church of Keila was destroyed at the Livonian War in 1558 and the interior was stolen. It was restored in 1596.
There are several chapels in the graveyard, which have been built after 1772 due it was no longer allowed to bury inside churches.

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.
