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:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
