Under the reign of Martino d'Aragone and Queen Maria, Nicolò D'Amico was granted the sea space to arm the tonnara under the castle in the inlet called Ngonia. From 1818 to 1756, the tonnara was owned by various families, including Marullo and Bonaccorsi. In 1970 it passed into the hands of Don Girolamo Calapaj, who managed it together with the D'Amico family until 1996. In that year, the tonnara ceased its activity.
Work in the tuna nets began in April with the customary 'going out on the flat' ('nisciuta in chianu'). After the blessing of the premises and staff, the boats were repaired by the shipwrights while the other workers worked on the revision of the nets. The tuna fishery was equipped with many boats, including the muciara, which was the rais's boat on which a flag was hoisted, the colour of which indicated the type of fish caught: white for swordfish, red for tuna; the 20-metre long palischermi without masts that were used to transport the tuna to the shore; and the smaller boats that carried the nets and tools. The small church, recently restored, was used to store nets and ropes during the Tonnara's months of inactivity. At the base of the votive aedicule, there is still a marble inscription that recalls that the tiny shrine was erected in 1907 'A Maria Consolatrice dai Marinari della Tonnara del Tono'.Behind the small church, in which the simulacrum of the Black Madonna of Tindari is venerated and within which an elegant and delightful paving dating back to the 18th century has recently been brought to light, a steep flight of steps allows one to walk to contrada Manica, where from the heights of the promontory one can enjoy another breathtaking view of 'Ngònia, the Castle and the entire western riviera.
Today, the small square of the 'Ngònia houses, towards the south, the old renovated warehouses that for centuries offered shelter to tuna boats. Facing the sea stand the buildings that belonged to the families who owned the Tonnara del Tono. The palace was commissioned in 1815 by Domenico Calapaj, as can be seen from some inscriptions legible in the freestone decorations, and was renovated by the Calabrese family.
Not far from 'Ngònia are the low buildings of the 'La Tonnara' residence, erected at the beginning of the 20th century to house the factory producing tuna in oil in tin cans, where mostly the wives of the 'Tunìsi', as the inhabitants of the district are called, found employment.
