Lokrume Church history dates back to the 12th century. The northern wall of the presently visible church nave dates from this century. Parts of the northern wall of the choir also date from this church. However, later reconstructions have reshaped the church and nothing more remains of this first, Romanesque church. During the second quarter of the 13th century, the larger part of the presently visible choir was built, with inspiration from churches in Visby. Slightly later is the rest of the nave and the sacristy. The last phase of the reconstruction was during the 1270s, when an earlier Romanesque tower was replaced with the presently visible one. The rebuilt church was inaugurated in 1277.
Internally, the church is sparsely decorated by frescos from the 1270s. During a renovation in 1957-62, fragments of 15th-century frescos were also discovered under layers of white paint, but these were too damaged to be restored. The frescos in the sacristy date from the 18th century. The altarpiece is from 1707, while the pulpit dates from the second half of the 17th century. The church furthermore has a triumphal cross from circa 1200, and a baptismal font by the artist known as Majestatis, dating from the later part of the 12th century. In the choir stands a choir bench made of parts dating from the 17th and 13th century respectively. Also in the choir is the tombstone of a judge name Gervid Lauks, dated 1380.
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.
