The University of Catania is the oldest university in Sicily and the 13th oldest in Italy.
The university was founded by King Alfonso V of Aragon (who was also King Alfonso I of Sicily) on 19 October 1434. Alfonso V with this gesture wanted to compensate the city (in which there had been recently established the Royal Court) for moving the Sicilian capital from Catania to Palermo. The activity of the Atheneum actually started a year later, in 1445, with 6 professors and 10 students. The first four faculties were Medicine, Philosophy, Canon and Civil Law and Theology. Lessons were initially held in a building in Piazza del Duomo, next to the Cathedral of St. Agatha, and eventually moved to the Palazzo dell'Università in the late 1690s. This building remains the seat of the university to this day.

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.
