Pirita Convent (Pirita klooster) was a monastery, for both monks and nuns dedicated to St. Bridget. In 1407 two brothers from St. Bridget Order Convent in Vadstena, Sweden, had arrived to Tallinn to promote with advice and other assistance the expansion of order to Estonia. In 1417 finally the first limestone quarry permit was obtained from the town with the help of the Grandmaster of the Livonian Order and the building of the Pirita convent started. The completed church was consecrated on August 15, 1436 by Tallinn’s Bishop Heinrch II.
The Pirita Convent operated over 150 years and was the largest nunnery in Old Livonia. It was brutally destroyed by Russian army short invasion in late January 1575. In addition, the nearby village was also destroyed. The local inhabitants never restored most of the buildings. As late as in last century – in the 1930s - potato field covered the former nuns quarters and the potatoes were stored in the former hypocaust of the abbess’s residence.
Today the beautiful park with the convent ruins is administrated by the Bridgettine sisters. The museum is opened year round.
References: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.
