The church of Santa Cruz de Arabaldo was originally a small monastery that depended on the important Cistercian community of Oseira: its documents date it as early as the 12th century. It consists of a single nave and rectangular apse.
Its façade is Baroque, but the rest of the stonework is Romanesque. Thus, on the southern façade we find a mysterious inscription with Romanesque characters and on the cornice some corbels with geometric decoration. On the northern façade, on the other hand, the corbels have vegetal decoration, and a checkered semicircular gate appears, supported by vegetal capitals and two bovines on the brackets.
The rectangular apse is lower than the central nave. Both end in a cornice supported by corbels: the southern ones have geometric shapes and a monstrous animal, while on the northern ones there is a person drinking from a barrel, an animal that seems to be looking at us and a bird clutching an object. The head has a semicircular arched window with checkered patteern supported by capitals (some decorated with birds) on smooth columns. The apse is finished off in an Agnus Dei with a ram whose cross is missing
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.
