Church of Santa Eulalia of the Monastery of Arnoso was originally founded in the 7th century on the initiative of San Frutuoso, Bishop of Dume and Braga. It was destroyed by the Moors in the 11th century. It was later rebuilt by King García II of Galicia.
It is a simple church in early Romanesque style with a nave, a barrel vault and a rectangular apse with blind arches. The wooden portal consist of round arches and a tympanum with a cross pattée. These round arches are profusely decorated with geometric, intertwined and zoomorphic elements.
Inside the church there are a few sixteenth century frescoes with episodes from the life of Our Lady. The two crosses on top of the roof show some similarities with Celtic crosses.
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.
