We went to The Association of Photographers general meeting in London and afterwards went down to Greenwich. There is a primary triangulation point at The Royal Observatory and we wanted to research exactly where it was. It appears to be on the roof ( if anybody knows different – please let us know) and by the time we got there the place was closing so we couldn’t gain access.There isn’t a concrete pillar but we assume there must be a fixed point of some sort.
We’ll go back in the summer. However, it was such a nice evening photographs across the park looked good.
