Castello Ursino was built between 1239 and 1250, as one of the royal castles of Emperor Frederick II, King of Sicily. In 1295, during the Sicilian Vespers, the Parliament which declared deposed James II of Aragon as King of Sicily, replacing him with Frederick III, was held here. The following year it was captured by Robert of Anjou but was later again in Aragonese hands.
After the move of the capital away from Catania and the appearance of powder weapons, the castle lost its military role and was used as a prison. It is one of the few buildings in Catania to have survived the earthquake of 1693.
The castle was acquired by the city of Catania in 1932, and it was restored. The Museo civico opened in the restored castle on 20 October 1934. Today, the museum houses artifacts and artwork from the castle as well as the greater geographical area. These items date from the Classical era onward, representing the diverse influences throughout Sicilian history. Frequently, the castle hosts also temporary exhibitions or artistic events (theatrical representations and concerts).
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.
