Old St Peter's Church is a ruined parish church in Thurso. It dates to at least 1125, and at one time was the principal church for the county, administered by the Bishops of Caithness.
Early in the 16th century, the vicarage of Thorso was held by Sir John Mathesoun chancellor of Caithness, on whose demission or otherwise Queen Mary in 1547 presented Master John Craig to the benefice. Master Walter Innes, who appears in record in 1554, was vicar of Thurso in 1560, and continued to hold the vicarage between 1561 and 1566. About 1567, John Rag was minister, and in 1574, Alexander Urquhart was minister of Olrik and Thurso, and John Davidsoun was reader at Thurso. In 1641, Alexander Monro, minister at Durnoch had from King Charles I, a grant of 800 marks Scots or of eight chalders victual in augmentation of his stipend from the rents of the bishopric in the parish of Thurso and elsewhere.
Old St Peter's, still standing, was disused since 1832 when a replacement church was built for the parish. That church, St Andrew's and St Peter's, is of Gothic style and was built to a design by William Burn.

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.
