The site of Crichton Collegiate Church may have been the location of an old Christian shrine. In about 1440 William Crichton, 1st Lord Crichton, Lord Chancellor of Scotland started to build a church there. On 26 December 1449 he opened the church. Like many other collegiate churches, Crichton was built for the use of the local lord, and a provost, eight prebendaries, two choir boys and a sacrist were appointed to pray for the souls of the Crichton family. The provost was granted the tiends and tithes of the prebends, the Rectory of Crichton and the Temple lands appertaining to Crichton.
The church was built in a Gothic and Romanesque cruciform style with a large central tower; the nave was used as the place of worship for the poor people. However the Crichton family supported the claimant Alexander Stewart, Duke of Albany, in the 15th century, fell out of favour with the Scottish Crown and the Crichton lands were forfeited. During the Scottish Reformation of 1560 the glass was taken from the windows, the floor converted back to earth and the medieval stone tracery destroyed. The chancel roof was still extant but the church was a ruin and considered unusable for services.
By 1569 it was being used as the parish kirk (church) and a minister, Adam Johnston, was ordained to lead the service. By the 1580s, major restoration work began, though the nave was said to be ruinous, as it is to this day. In 1641, by an Act of Parliament, Crichton Church was declared to be the parish church for all time. Though there was more restoration and adaptation in 1729 it was considered to have been carried out 'badly'. More work in the 1820s helped to bring the old church back to life, but it was not until the end of the 19th century that the church was fully restored, by the Edinburgh architects Hardy & Wright. Stained glass windows made by the Edinburgh company Ballantine and Gardener, new oak pews and a pipe organ built by the Glasgow company Joseph Brook were installed. The Church of Scotland closed the church in 1992 and the Crichton Collegiate Church Trust acquired the property. The Trust restored the organ, stained glass windows, lighting and the tower.
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.
