According to some historical sources, Dragonara Castle was built in the first half of the 13th century. In the second half of the 14th century, the castle, to ensure the safety of the fishing village of Camogli, was repeatedly reinforced, receiving the necessary weapons from the Republic of Genoa.
In the 14th century, the Dragonara Castle was attacked several times. Well documented are the assaults made by Gian Galeazzo Visconti, Lord of Milan, and the one made by Nicolò Fieschi in 1366.
Between 1428 and 1430, the castle was considerably enlarged and reinforced, especially the adjacent watchtower. In 1438, the Duchy of Milan besieged the castle, destroying its walls. A few years later, the inhabitants of the seaside village built new walls around the castle.
In 1448, due to a conflict between Camogli, Recco and Genoa, the Republic demanded the immediate destruction of the castle. The castle was destroyed, but it was rebuilt again only six years later and given to the Doge of Genoa.
In the 16th century, the castle was abandoned as a defensive post, and it was used as a prison.
In the seventies of the 20th century, after decades of neglect, the building was recovered and converted into an aquarium, hosting specimens of the marine fauna typical of these waters. At the closing of the aquarium, the fish were transferred to the Genoa aquarium.
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.
