The Romanesque Santo Domingo Church was built in the late 12th century above a pre-existing church dedicated to San Tomé, although it was partially renovated in the following centuries, including the century transept and choir area, added in the 16th century when a Dominican convent was founded annexed to the church.
It has a façade with two orders of arcades at the sides of the portal, which is surmounted by a rose window. The portal has an elaborated archivolt with Biblical characters and scenes, including the 24 elders of the Apocalypse, the Massacre of the Innocents, the Youth, the Passion and the death of Christ. The tympanum has representations of the God the father sitting with the Child, four angels with the symbols of the Evangelists, the prophet Isaiah and the Virgin Mary. The capitals on the jambs of the entry feature biblical scenes from the Genesis and the life of Christ.
The interior is on the Latin cross plan with a nave and two aisles, covered by barrel vaults.
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.
