Baldringe Church was built in the late 1100s or in the beginning of 1200s in Romanesque style. The restoration was made in 1880s and some medieval mural paintings were removed. The bell tower was also added then.
The baptismal font, made of limestone of Gotland, date from the 1200s as well as the triumph crucifix. The pulpit and altar were made in the 1600s. There is also a Viking Age runestone, so-called Baldringestenen, in the churchyard.
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.
