The Dominican monastery was founded in 1246 and it is the oldest one in the medieval old town. The center of monastery was St. Catherine's Church, which was completed in the late 1300s and was the largest church building in the lower town. The Monastery was expanded several times, most recently in the 16th century.
St. Catherine's convent closed down in 1525, when the monks were expelled from Tallinn during the Reformation. The looted and empty monastery church was destroyed by fire in 1531 - only ruins were left.
There were originally three inner chambers (together so-called claustrum) in the monastery allowed only for residents. The claustrum housed the most important rooms in the monastery: the prior’s room, the old library, the chapter hall, the dormitory, the sacristy, the cloister and the vestry. In the 14th and 15th centuries the leaders of the knight guilds of Harju and Virumaa often used the claustrum as their meeting and gathering place.
Only the eastern chamber has been preserved to our days. The dormitory, library, dining room and other rooms provide a fascinating opportunity to take a peek into the life of medieval monks. A mysterious "energy column" is located in the basement. According the legend it can be a source of physical and mental well-being.

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.
