The Archaeological site of Mount Bonifato is located in Alcamo. According to Licofrone of Alexandria, there was a village called Longuro on Mount Bonifato of Alcamo in ancient times. This settlement had been founded by a colony of Greeks who had escaped from Troy.
The archeological site was probably inhabited from the 7th century BCE to the 12th century AD. From the 6th century BCE Mount Bonifato very probably had the status of a satellite to the nearby town of Segesta. Further, the site shows unusual traces of human settlement during the period of the Roman Empire. After the 3rd-2nd century B.C. the Romans directed their interest towards the vale of the mount and along the coast of the gulf of Castellammare, to the west along the valley of the Fiume Freddo (later Fiume Caldo), and to the east to the valley of the Finocchio and Calatubo torrents.
The walls brought to light testify to a continuous presence from the 9th century on. When the Arabs came to Mount Bonifato, they chose to build their houses in the same place where those of former periods had stood. Moreover they found a safe place here, and adequate resources for a lifestyle suited to their family units, thanks to the presence of water.
The cisterns of the medieval era date back to the 13th century. The date is confirmed by the construction techniques used and by the finding of green glazed ceramics of that period. The work on their recovery and restoration involved the removal of the humus and other material which completely filled both cisterns. Cistern A, about 4 metres high and 6 metres long, was used by various unicellular houses. Cistern B, which is smaller than the other, is about 2.85 metres by 4.30 metres.
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.
