Plasencia Cathedral consists of two buildings: the old (Catedral Vieja), dedicated to Saint Paul, and the new (Catedral Nueva). Construction began in the 13th-century in a mostly Romanesque style. The 15th-century new church was built in Gothic architectural style with high ceilings. The main retablo was built in the 17th-century, carved by Gregorio Fernández and painted by Francisco Ricci. The choirs are delicately carved. The old church now houses the Cathedral museum.
The Old Cathedral is an example of a transitional building from Romanesque to Gothic architectural styles. To the Romanesque style belong the fustis and capitals of its columns, while to the Gothic style belong its arches and windows, discovered in one of the most recent restorations. Its three naves were covered from the 18th century by a thick mantle of lime, which only after decaying has allowed observers to admire the slenderness of a solemn cathedral.
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.
