Carcassonne Cathedral was built in the 13th century as a parish church, dedicated to Saint Michael. Following war damage in the 14th century it was rebuilt as a fortified church. In 1803 St. Michael's was elevated to cathedral status, replacing the earlier cathedral dedicated to Saints Nazarius and Celsus, now the Basilica of St. Nazaire and St. Celse.
The cathedral plan is characterised by its relative simplicity. It forms a single nave with a 20 metre high vault, lined with several lateral chapels. The chior screen has retained its 14th century stained glass. The sober façade has a single decorative feature in the form of a large rosette 8 meters in diameter, and the adjoining bell tower is relatively massive.
References:Duino Castle was built by the Wallsee family in 1389 on the cliffs overlooking the Gulf of Trieste. It replaced an older castle from the 11th century. Over time, the Wallsee family disappeared and the castle, after having been used as a prison, became the residence of the Luogar and Hofer.
At the end of the 19th century it became the property of Prince Alexander von Thurn und Taxis from the Czech branch of the House of Thurn and Taxis. It remains with the family to this day with his great-grandson Prince Carlo Alessandro della Torre e Tasso, Duke of Castel Duino the current owner. The castle has been opened to the public as a museum and park.
