Palazzo Santa Sofia is known as Ca' d'Oro ('golden house') due to the gilt and polychrome external decorations which once adorned its walls.
The palace was built between 1428 and 1430 for the Contarini family, who provided Venice with eight Doges between 1043 and 1676. The architects of the Ca d'Oro were Giovanni Bon and his son Bartolomeo Bon.
Following the fall of the Venetian Republic in 1797, the palace changed ownership several times. One 19th century owner, the ballet dancer Marie Taglioni, removed the Gothic stairway from the inner courtyard and destroyed the ornate balconies overlooking the court.
In 1894, the palace was acquired by its last owner, baron Giorgio Franchetti; throughout his lifetime, he amassed an important art collection and personally oversaw its extensive restoration, including the reconstruction of the stairway and the Cosmatesque courtyard with ancient marbles. In 1916, Franchetti bequeathed the Ca' d'Oro to the Italian State. It is now open to the public as a gallery: Galleria Giorgio Franchetti alla Ca' d'Oro.
The principal façade of Ca' d'Oro facing onto the Grand Canal is built in the Bon's Venetian floral Gothic style. Other nearby buildings in this style are Palazzo Barbaro and the Palazzo Giustinian. This linear style favoured by the Venetian architects was not totally superseded by the Baroque one until the end of the 16th century.
On the ground floor, a recessed colonnaded loggia gives access to the entrance hall directly from the canal. Above this colonnade is the enclosed balcony of the principal salon on the piano nobile. The columns and arches of this balcony have capitals which in turn support a row of quatrefoil windows; above this balcony is another enclosed balcony or loggia of a similar yet lighter design.References:
The Château Comtal (Count’s Castle) is a medieval castle within the Cité of Carcassonne, the largest city in Europe with its city walls still intact. The Château Comtal has a strong claim to be called a 'Cathar Castle'. When the Catholic Crusader army arrived in 1209 they first attacked Raymond-Roger Trencavel's castrum at Bèziers and then moved on to his main stronghold at Carcassonne.
The castle with rectangular shape is separated from the city by a deep ditch and defended by two barbicans. There are six towers curtain walls.
The castle was restored in 1853 by the architect Eugène Viollet-le-Duc. It was added to the UNESCO list of World Heritage Sites in 1997.
