Sometimes quests come to you unexpectedly. I was looking for the source of the Mar Dyke on Google Map and spotted a heritage marker in a field near the village of Bulphan in Essex. Zooming in on the map to see what artefact or building was to be found, it simply read ‘Easternmost Point of Greater London’. I had to go and see what was there.
The journey to the eastern edge of Greater London starts on the Romford to Upminster Overground line (to be renamed the Liberty line) and then goes along St Mary’s Lane to Thames Chase Community Forest, crosses the M25 to St Mary Magdalene in North Ockendon then picks up Fen Lane to the border of Greater London on the banks of the Mar Dyke, in the London Borough of Havering.
