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 Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
