Illustrated in the postcard is the "Portcullis", the gateway to the Bloody Tower. The walls around and above the gateway appear to be made of stone. Two narrow rectangle windows can be seen on the right side of the wall, with a drain pipe coming from the top down the side of the windows. They look as though there are bars on these windows. According to the information found on the internet the portcullis were important as a last stand in defenses guarding the land entrance to the fortress. Steel spikes projected from the frame can be seen, the machinery to raise and lower the portcullis was housed in the room above. On the other side two men can be seen visiting. The side of another building is to their right.
