I have no idea what these objects in the sea are! I imagine the distant ones are buoys for shipping. I am pretty sure the larger structure also has something to do with shipping but as it is so close to the Cardiff Bay barrage, where we were walking, I am not sure what its purpose is. It has meteorological equipment on it and clearly it is a convenient pirch for birds – other than that all I can say is that I like the composition of uprights, horizontals and perspective in this shot.
