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:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
