The church of Santa Maria in Araceli is a late-Baroque style church built in the late 17th century in Vicenza according to designs attributed to Guarino Guarini. Construction of the present church was begun during 1672-1680, a period during which the famous architect Guarino Guarini resided in Vicenza under the patronage of the Theatines. In 1965, designs for the church were found in the Vatican Library. Construction seems to have been guided by Carlo Borella. It was about 60 years after the start of construction, on November 17, 1743, that the church was consecrated. In 1810, during the Napoleonic occupation, the convent was expropriated, and the church became a parish church.
The main baroque altar (1696), was carved in marble by Tommaso Bezzi . It contains an altarpiece representing the Tiburtine Sybil who portends the coming Virgin and Child to the Roman Emperor Augustus attributed to Pietro Liberi . The altar on the right has a 13th-century painted crucifix, originally from church of San Vito.

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.
