The Little Mermaid of Golfo Aranci on the Italian island of Sardinia is known as La Sirenetta Di Golfo Aranci, but also as "Il canto della Sirena" (the Siren's Song), because she appears periodically accompanied by Sardinian songs in a unique multimedia arrangement for crowds and visitors on shore. map
The sculptor Pietro Longu created the sculpture "The Chant of the Mermaid" for the new seafront of Golfo Aranci. The sculpture depicts a slender and sinuous Sardinian mermaid emerging from the water at set times of the day, accompanied by the melody of a Sardinian chant as she greets the inhabitants of the town, the fishermen, and the tourists.
Pietro has stated that the sculpture is a tribute to the uniqueness of the Sardinian woman. She is strong, wise, discreet, patient, graceful and courageous. She is a pillar of the Sardinian family and society, and she has been a source of fascination and inspiration for the Sardinian man since prehistoric times.
She reaches for the sky and the stars, and surrenders to them with her head leaning in a romantic expression.
The sculpture is made entirely of bronze and is 3.5 meters (11') high and weighs 5 tons.
As far as I know this is the only mermaid sculpture anywhere that mechanically rises out of the sea, as you can see here
