The Romanesque church in Kalinčiakovo is a Reformed chapel, originally built in the 12th century in the Romanesque style. The building has been the property of the Reformed Church in Slovakia since 1655.
After a fire damaged the building, the chapel was rebuilt between 1833 and 1835, with further renovations in 1932 and from 1957 to 1958. The 1833 fire revealed some frescoes depicting celestial bodies and animals.
The church is built from hewn stones and strengthened with stooks. The typical Romanesque semicircular apse is vaulted by concha. The apse is continued by aisle. The Romanesque windows survived the fire. In 1932 the Romanesque portal was revealed on the south frontlet. The Classicist organ dates from 1833. Originally the church was enclosed within a fortress wall of which only a slightly rising entrenchment remained.
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.
