Dominique Appia began painting at the age of 40, as an autodidact.The artist signed several wall decorations, including the ceiling of Victoria Hall, in Geneva, in 1987. He had repainted this ceiling after the fire of 1984. The fresco which appears there extends the auditorium.
The general public liked the figurative works of this self-taught painter with meticulous design and dreamlike breath. Dominique Appia transfigured his city in a pictorial register close to surrealism.
In addition to acrylic paintings, Dominique Appia has also produced theater and opera sets, exhibition posters and illustrations. Elements of his birthplace, the harbor, the Salève, the Saint-Pierre cathedral or the water jet, appear in his often dreamlike compositions.
In 2013, Dominique Appia published "Geneva. Loving and sentimental guide for the curious", published by Slatkine. A documentary film directed by Nasser Bakhti was dedicated to him in 2015.
