In the 1920s Mario Tozzi, together with Severini, De Pisis and a small group of other artists, was one of the italiens de Paris, Italian painters, residents in Paris, who united Italian style with the avant-garde of the era. The painter had grown up in Suna and he returned several times in his life, residing there for long periods, and linking his art to some works that can still be admired in the Verbanese hamlet today.

Among these are eight roundels, made with the oil on canvas technique, each measuring just over a metre in diameter. They can be admired by entering the church of Santa Lucia and raising your eyes towards the vault. Created between 1923 and 1924, they are dedicated to Santa Lucia da Siracusa and to episodes of her life, to Sant'Andrea da Avellino, San Francesco d'Assisi and San Mauro.

The 16th century church that houses these works was built as an oratory overlooking the Suna lakefront, the date 1585 is still visible on the bell tower. The historic centre of Suna, with its maze of narrow alleyways, lies behind the parish church. It houses precious ancient frescoes, petroglyphs and evocative murals of recent construction on the walls of some buildings.

Directly in front of the church, close to the lake shore, stands another testimony of the bond between Tozzi and Suna. The First World War Memorial, an arch in exposed stone blocks, framing the Borromeo Gulf, flanked by a dying soldier placed on a pedestal. It was designed by the artist in 1951 and inaugurated in 1953.
