The early medieval Parish church of St. Martin Busskirch with its cemetery rests on the remains of a Roman building (1st to 4th century AD). It is one of the oldest churches around the Lake Zürich. Even the citizens of Rapperswil had to attend services in Busskirch until Count Rudolf II of Rapperswil built his own church and a chapel next to Rapperswil Castle in 1253.
In 1351 St. Martin Busskirch was incorporated by the monastery (until 1838). In co-operation with Jona the settlement formed an Allmendgenossenschaft (farmer's association), reigned by the Counts of Rapperswil, latter by the city of Rapperswil. In 1253 the parish churches of Rapperswil and Jona were established: St. Martin Busskirch lost its former importance and was in 1945 integrated in the Roman Catholic parish Rapperswil.
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.
