This is the Beach of Capo Graziano, in Filicudi Island
In this 180° panoramic picture you can see both Pecorini
(on the left) and Capo Graziano
on the right.
The wall of rocks you see in the middle of this picture is not really
curved... it's just an optic distortion due to the panoramic format of
the image.
On the extreme left you can see the skyline of Alicudi
Island, on the extreme right, covered by some clouds you should be
able to recognize from left to right Salina, Lipari and Vulcano.
Here is again Pecorini seen from Capo Graziano Beach.
Give a look here
if you are interested in the history of Filicudi Island and of course
"Capo Graziano".
It will open another window on the Filicudi section in the web site
of the Museum of Lipari.
