We have now meandered our way over to the tip of the troubled northeast bastion: This is the one made of concrete, awaiting not only a stone façade, but also a stone lip that serves as firing crenellations and a bit of a safety railing for idiots who get too close to the edge. As it is my firm policy to get a pic of my feet at the tip of every bastion with which I come in contact, this was the best I could do with the non-period fencing along that bastion's edge.
