An amazing gate in the middle of a stone wall.
The inner walls are lavishly covered with different nautic flora and sponges. Urchins sit at the top on the left and on the middle right, a rounded green Codium bursa alga is growing at the top corner. In addition, there are at least three fishies on this picture: a silver stain with a dark dot at the left wall, a dark stain uppon the floor and a green back of a fish sitting among Posidonia oceanica seaweed is viewable a little higher.
