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:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
