The location of this boundary marker is shown in Image and Image There were originally nearly 280 coal tax posts located around London, of which about 210 are still extant; around 180 of these (85%) are 3 ft high white-painted square bollards with a pyramidal top, decorative raised bands, and the shield from the City of London’s arms. Photos of the coal tax posts on Geograph are at http://www.geograph.org.uk/search.php?i=86542993&page=1 . There are just 4 extant markers in situ of the type shown in the photo; the other three are Image, Image and Image The only other example is in a museum. The posts were erected under the Coal and Wine Duties (Continuation) Act of 1861 to mark the points at which duty had to be paid on coal being transported to London. The boundary was set at that of the Metropolitan Police District, and the resulting revenue was used by the Corporation of the City of London to fund public works.
