Pylos
Pylos nowadays is a small, pleasant place with a huge fortress and an interesting museum.
Pylos is very strategically situated with a huge natural harbour, where the famous battle of Navarino took place.
Here, in 1827, a European fleet (England, France, and Russia) destroyed the holed-in Egyptian fleet of Muhammad Ali, who came to the aid of the Turkish Empire in the Greek war of independence.
More on the battle of Navarino at Wikipedia.
In the picture you can see part of the small opening of the huge bay with Sphacteria island to the right.
I took this photo using a polarizing filter on Fuji Velvia.
