History
Origins in Coastal Defense
The Castle of Bonassola is a sixteenth-century defensive fortress in Bonassola, Italy, built under the Republic of Genoa in 1561 to protect the village and the surrounding coast. The Republic of Genoa was a maritime state that controlled territories and coastal settlements in Liguria. Increasing raids by Barbary pirates, privateers and raiders operating from the North African coast, led residents of Bonassola, Montaretto, and San Giorgio to meet at the church of Framura on 23 February 1557 and discuss a shared defensive position.
Further attacks on the church of San Giorgio in 1560 and 1561 encouraged plans for a tower near Bonassola’s marina. Disagreements between the villages, especially over the proposed building site, brought direct intervention from the Genoese Senate. Two officials were sent from Genoa to address the dispute. On 12 December 1561, a report concerning the possible construction of the castle reached the Senate, which decided that it should stand on a hill behind the village.
Military Use and Later Transformation
The castle continued to serve a military purpose under Genoese rule and through the later governments that controlled Liguria. These included the Ligurian Republic, the French-backed state that replaced Genoese rule in 1797, followed by the Kingdom of Sardinia and the Kingdom of Italy, established in 1861. Its original defensive function ended in the nineteenth century.
During the nineteenth century, the former fortification was converted into a small cemetery. Further structural alteration took place in 1963, when the railway was relocated inland. The Municipality of Bonassola owns the castle, which has held Italian national heritage status since 1934.
Remains
The surviving castle stands on Vicolo Chiuso dell’Orologio behind Bonassola’s historic center. Its building has a square plan with two circular towers positioned at its corners. A public clock forms part of the structure, which is currently in good condition.
