Herford Abbey was the oldest women's religious house in the Duchy of Saxony. It was founded as a house of secular canonesses in 789, but moved later to the present site. The city of Herford grew up on this site around the abbey. The abbey was dedicated in 832 and was elevated to the status of a Reichsabtei ('Imperial abbey') under Emperor Louis the Pious (d. 840).
Between 919 and 924 Herford was destroyed by Hungarians but was rebuilt by 927. In 1147 the abbey, which by this time had almost 850 estates and farms, was granted Imperial immediacy. This made it an independent territory within the Holy Roman Empire which lasted until 1803.
In 1533, during the Reformation, Herford Abbey became Lutheran, under the Electors of Brandenburg. From 1649 for over a century the abbesses were all Calvinist but that did not alter the Lutheran character of the principality.
In 1802 the abbey was dissolved in the course of secularisation. In 1804 it was turned into a collegiate foundation for men, and in 1810 finally suppressed. The former abbey church remains in use as Herford Minster (Herforder Münster). The church is a late Romanesque hall church, built about 1220-1250. It is one of the earliest hall churches in Germany.
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.
