The Castle of Pietrarossa ('Red Stone Castle'), built using, as its name suggests, largely red stones, dominates the city and the whole Salso River valley from the edge of the ravine upon which it stands.
The originsa castle remain unknown. It is presumed to have been built in the 9th century, but there are some historians who claim that it was built by the Sicani, a people that was present in Sicily in the 8th century before the arrival of the Greeks. The castle is towering over the whole valley of the river Salso.
Throughout history some historical events took place, in 1378 an important meeting of the Sicilian barons was held during which 4 were appointed vicars to govern Sicily. Around 1570, a strong earthquake destroyed most of the castle, today there are only two towers left.
The view that you can admire from this castle is spectacular although today the castle is in a state of disrepair. So be very careful when visiting.
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.
