San Marcos is a Gothic church in Jerez de la Frontera. It originates from one of the six parishes founded by King Alfonso X of Castile after his conquest of the city in 1264. The current edifice was likely started in the mid-14th century, due to the style of its polygonal apse and the Mudéjar portal, perhaps above a pre-existing mosque. The construction is anyway not documented until the middle of the 15th century, including a substantial renovation in late Gothic style.
The church has three façades, with a main entrance portal in Mannerist style (16th century). The interior has a Baroque high altar (18th 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.
