Emma T., Gavin T. and Keenan L. all gave brief descriptions of the structure - I suppose the next question should be - how many rods of what lengths have been used to make this frame?

All of them identified the shape as a climbing frame. It has a hexagon shaped base with horizontal bars connected to vertical bars all like steps going upwards and no top. The sun is hitting it on the left side making the shadow fall onto the right.
