This plaque was brought to our attention by Antoinette Ward and had us foxed. It was destined for Puzzle Corner but then Matt of Londonist came up with the answer. It's a marker for the boundary of the Tower Liberty. And Ian Visits has recently explained how this and the other markers of the Liberty are beaten.
