And you should also note that the location where they charge you to take that photograph is about 20 meters to the west of where it should be. At least, I presume my modern smartphone's GPS is fairly accurate, as well as having looked it up on Google Earth later.
I always thought that the meridian line as marked is 0° in *OSGB36*, not WGS84 which is what GPS uses: http://theconversation.com/heres-why-the-greenwich-prime-meridian-is-actuall... http://metro.co.uk/2015/08/15/oops-the-greenwich-meridian-line-is-in-the-wro... cheers, Derick
