The nave and tower are the oldest parts of the church in Lummelunda. They were both erected circa 1200. Originally, a choir built at the same time formed part of the church. This choir was razed in the middle of the 14th century, and the presently, disproportionally large choir was built instead. The rebuilding of the choir was intended as the beginning of a complete reconstruction scheme, but only the choir was executed. The church has remained largely unaltered since then. The sacristy is of unknown date, mentioned for the first time in 1739, and the church spire dates from 1636. During the 17th century, new windows were added to the nave, it received new furnishings and was re-decorated inside. The windows were again altered during the 19th century.
Architecturally, the church is characterised externally by the large Gothic choir and the much smaller Romanesque nave and tower. It is built in limestone. The main, southern portal is decorated with stone sculptures similar to those of Martebo Church, but somewhat cruder in execution. Internally, the church is decorated with frescos. Of these, some date from the construction period of the church, some from the 15th century and some from the 17th century. The church houses a single, rather worn late medieval wooden sculpture depicting Saint Anthony. Most other furnishings are from the 17th century.
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.
