The Sirenusas (Italian: Le Sirenuse), also known as the Gallos (Li Galli, "the Cocks"), are an archipelago of little islands off the Amalfi Coast of Italy between Isle of Capri and 6 km (4 mi) southwest of Province of Salerno's Positano, to which it is administratively attached. They are part of the Campanian Archipelago. The name, Sirenuse, is a reference to the mythological sirens said to have lived there.
The archipelago consists of three main islands:
- Gallo Lungo, which takes the form of a dolphin
- La Castelluccia, also known as Gallo dei Briganti
- the nearly circular La Rotonda
Several sirens were said to have inhabited the islands, the most famous of whom were Parthenope, Leucosia, and Ligeia. One of them played the lyre, another sang, and another played the flute. They are mentioned in the 1st century BC by Strabo, the Greek Geographer and by Straton of Sardis in 120 AD. In ancient stories, the sirens were depicted as having bodies of a bird and human heads, but the medieval interpretations of the stories depicted them as mermaids.
The terms Sirenai and Sirenusai, from the Latin Sirenusae, meaning indicate both the sirens themselves and their residence.
The modern name, I Galli or The Cocks, references the bird-like form of the ancient sirens.
Originally Gallo Lungo hosted a monastery and then a prison. During the reign Charles II of Naples (late 13th century), the Amalfi coast became subject to increasing attacks by pirates. To deter them, Charles wished to build a watchtower on top of the remains of a Roman tower on Gallo Lungo. As he lacked sufficient funds he accepted an offer from Pasquale Celentano of Positano to lend the required funds, in return for being appointed warden of the fortification. The tower (today called the Aragonese Tower) was constructed around 1312  and occupied by a garrison of four soldiers. The wardenship was subsequently passed to Angelo Balbo in 1382 and in 1425 to Viviano Mirelli. Responsibility for the islands then passed to Catalian Gilberto Squanes, the Miroballo family and then to the Marino Mastrogiudice before passing to the crown and then the Marquises of Positano. Eventually with the establishment of the Republic of Italy ownership passed to the town of Positano. The town later sold the islands to a native of Salerno who sold them to Davide Pariato.
In 1919 the Russian choreographer and dancer Leonide Massine sighted the islands while staying with a friend in Positano. In 1922, he purchased Gallo Lungo and began converting it from a place of defense into a private residence. Initially Massine restored and converted the old Aragonese Tower on Gallo Lungo into accommodation with a dance studio and featuring an open-air theatre. The theatre was subsequently destroyed by a storm. With design advice from his friend Le Corbusier he constructed a villa on the site of the original Roman structure . The villa featured the bedrooms facing Positano with a large terrace garden on the first floor facing Cape Licosa and Capri.
Shirley Hazzard in her book Greene on Capri recounts a visit to Massine.
After Massine’s death the islands were purchased in 1988 by Russian dancer Rudolf Nureyev, who spent the last years of his life here. He redecorated the villa in the Moorish style and clad its interiors with 19th-century tiles from Seville. He also installed a desalinization plant which provided a reliable water supply to and assisted in the development of the gardens,
After Nureyev’s death the islands were purchased from his foundation in 1996 by Giovanni Russo, a Sorrento hotelier who besides using them as a private residence also makes them available for private rental with a staff of 7 and a launch to take guests to and from the mainland. Members of the public are not allowed to land but can swim in the surrounding waters.
Isca has a villa and garden on the side facing the cliff (and, thus, not visible if sailing behind the island). The island was described by the playwright’s wife, Isabella, in a book entitled, In mezzo al mare un'isola c'è... ("There is an island in the sea…").

he says that there were three Siren islets. Now if Isca be omitted from this group, as lying too near the land, there is still the large rock of Vetara close to the Galli which cannot be overlooked and which raises their number to four.
