These splendid geological formations undoubtedly the best known feature of the island's jagged form - hold the numerous nests of Capri's large diomedei gulls. The first outcropping (Stella, or "Star ) is joined to the coast and stands 109 m. high; the second (di Mezzo, or "Middle') is 81 m. high and has a natural tunnel roughly 60 m. in length that passes right through it, the third faraglione (reef), is 104 m. high and inhabited by the blue lizard (lacerta muralis coerulea), now a rare, protected specie.
A fourth faraglione, standing by itself in front of the Port of Tragara, is called the Monacone, named after the sea lion or "Monaca' ("Nun') seal that lived there until the last century.
The remains of Roman structures - which actually consist of an access stairway and a tub for collecting water and raising fish - have contributed to the legend that Masgaba, the African architect of the island's Augustan buildings, was buried there.
