David I granted the chapel at Corstophine to Holyrood Abbey in 1128. By 1158, it had become a church, with altars to Saint Anne and the Holy Trinity.
A burial chapel was added to the church in 1404 by Sir Adam Forrester, who died by 1405. The chapel was dedicated to John the Baptist. The chapel was erected into a collegiate church by his son Sir John Forrester.
The foundation of the current church (on the inner eastmost wall) says the church was built in 1429 in the same churchyard as the earlier parish church, and was completed by 1437. The sandstone church was built with a tower and stone, octagonal spire, rectangular chancel, and a nave with transepts. This included the absorption of earlier Gothic features from the previous building and the erection of the characteristic barrel vaults, which may have concluded by 1436.
In 1634, the collegiate church was dissolved and in 1646 the building became the parish church. At that time the 12th-century church was razed and a new aisle was added to the collegiate fabric.Stones from the former church were used to built the porch. In 1828, a restoration by architect William Burn resulted in a two-storey sacristy, renovation of the nave, removal of a 17th-century aisle, and building of a new aisle and transept.

The church has Scottish heraldic panels and pre-Reformation relics. James Ballantine supplied the Victorian stained glass and Gordon Webster and Nathaniel Bryson supplied the 20th-century windows. Leonardo da Vinci's Last Supper was the inspiration for the heads on the carved corbels made by William Birnie Rhind. On the grounds are a war memorial, vault and gatehouse, surrounded by a boundary wall and cast iron gates.
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.
