Lärbro Church was probably built between 1260-1280. The unusual octagonal steeple was erected in the 1300s. The interior date made mainly from the times after Reformation. The murals in the church vaults are originals. In the chancel floor, by the chancel portal, there is a tombstone in memory of Nicolaus (Nils) Taksten from 1274.
To the west of church is a defence tower, which dates from the 12th century. It was built several storeys high with a lavatory on the third floor. Today, the defence tower is used as a belfry.
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.
