Eufemio Castle is mentioned in several historical sources, the oldest dating back to the first decades of the 12th century. It was described as an important place for the old town, thanks to its strategic position. In the 13th century, the importance of the Eufemio Castle grew considerably, as it was one of the main ones imperial castles of the reign of Frederick II of Swabia, whose guards guarded him during the battle against Muslims, who resided near the historic Segesta.
In the following centuries, the Eufemio Castle was inhabited by the various feudal lords who took turns at the command of Calatafimi Segesta, up to the 19th century, where it was used as prigione. Eufemio Castle remained in operation until 1868, only to be totally abandoned to itself, causing its state of degradation which, over time, saw the collapse of many of its parts. Today it is partially restored.
The Eufemio Castle would have been equipped with three towers, two still visible today in its remains, while there is no trace of the third, a fate shared also with the walls who would have wrapped it up to improve its defense system. Once you entered the Eufemio Castle, on the left there would have been the prisons, some walls of which have still been left engravings made, in all probability, by the prisoners themselves while serving their penalties. The Eufemio Castle would also have had a upper floor, which would have been used as a residence for the reigning feudal family.

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.
