St. John's Abbey in the Thurtal was a Benedictine monastery originally established in the mid-12th century. The oldest written record of it is dated October 4, 1152, when Pope Eugene III took the monastery into his protection. The pope confirmed the monastery's possessions and free election of its abbot and Vogt.
On October 24, 1178, Pope Alexander III confirmed the abbey's extended possessions. In 1227/1228, the king became Vogt of the abbey. In December 1231, Emperor Frederick II issued a Golden Bull confirming his obligations as Vogt of the abbey.
The abbey also frequently bought land in the territory which is now the principality of Liechtenstein, most notably the prominent Red House in Vaduz, which it purchased in 1525 from the heirs of the medieval owners, the Vaisli family.
The abbey's high point was during the 14th century. It survived the Reformation, but lost its independence in 1555, when it became a priory of St. Gall's Abbey.
In 1626 the buildings were severely damaged by fire, and the monks were afflicted by a mysterious illness and the community moved along the valley to a new location at Sidwald near Nesslau, since then known as Neu St. Johann. On the site of the old monastery a parish church was built, with a priest's house.
The new monastery buildings in Nesslau, which were completed by 1680, were in a magnificent Rococo style. Toggenburg was an area of mixed denominations, and the priory was an instrument of the Counter-Reformation under the leadership of the Prince-Abbots of St. Gallen.
The priory was dissolved in 1805. The former monastic church became the Roman Catholic parish church of the parish of Neu St. Johann. The remaining buildings now accommodate a remedial educational centre known as the Johanneum.
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.
