The Bridge of Sighs (Ponte dei Sospiri) passes over the Rio di Palazzo and connects the New Prison (Prigioni Nuove) to the interrogation rooms in the Doge's Palace. The enclosed bridge is made of white limestone, has windows with stone bars, and It was designed by Antonio Contino and was built in 1600.
The view from the Bridge of Sighs was the last view of Venice that convicts saw before their imprisonment. The bridge's name, given by Lord Byron as a translation from the Italian 'Ponte dei sospiri' in the 19th century, comes from the suggestion that prisoners would sigh at their final view of beautiful Venice through the window before being taken down to their cells. In reality, the days of inquisitions and summary executions were over by the time the bridge was built, and the cells under the palace roof were occupied mostly by small-time criminals. In addition, little could be seen from inside the bridge due to the stone grills covering the windows.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.
