The Casa de las Conchas is a historical building in Salamanca. It currently houses a public library. It was built from 1493 to 1517 by Rodrigo Arias de Maldonado, a knight of the Order of Santiago de Compostela and a professor in the University of Salamanca. Its most peculiar feature is the façade, mixing late Gothic and Plateresque style, decorated with more than 300 shells, symbol of the order of Santiago, as well as of the pilgrims performing the Way of St. James. In the façade are also the coat of arms of the Catholic Monarchs and four windows in Gothic style, each one having a different shape. The entrance portal has the coat of arms of the Maldonado family, while in the architrave are dolphins, a Renaissance symbol of love, and vegetable elements.
The inner court is characterized, in the lower floor, by arches supported by square pilasters, while in the upper ones they are supported by shorter columns in Carrara marble.
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.
