The chapel in Saha used to be one of the oldest ecclesiastical centres of Rävala Maakond (Shire). Originally, Saha Church was made of wood, it was burnt down around 1223. Four cult stones with small hollows dating from the 1st millennium BC, located close to the chapel indicate that it had been an ancient cult place. The current chapel was built by builders from Tallinn in the second quarter of the 15th century.
Structurally, the chapel bears striking similarities to Pirita Klooster. This simple double-vaulted parallelogram-shaped buiding is slightly asymetrical. Several construction details, like very high placed windows, a corner tower, a high gable roof etc., show that in addition to serving as the house of god, the Chapel had other functions as well. In case of necessity it could become a fortified stronghold protecting against enemy attacks, a resting place for pilgrims or a storage room for merchants. The chapel was badly damaged during the Great Northern War and was restored as recently as 1962-1969.
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.
