Iranian Ship Roundabout.

1973 saw the first Karman class fast attack naval ship commissioned by Iran.
That then begs the question as to why would anyone want to build a Karman class ship replica made of now crumbling concrete and rusty steel sailing in a slimy green soup in the middle of a roundabout when the nearest port is 260km away?
Not sure but as an art piece it makes an unusual sight.
