According to the A-Z, the furthest up you can go in London is Tilekiln Ossiers. It’s a small rhomboid of low deciduous woodland cut in twain by the M25. The northern edge of the motorway itself marks the boundary line, so we’ve included a Street View from this spot. If, for some reason, you’d like to go see this blessed patch for yourself, Crews Hill station is within a kilometre. Surprisingly, there’s a tourist attraction nearby. Diamond Geezer visited the little-known Whitewebbs Museum of Transport late last year. View in maps.
To reach London’s antipole, we must trek down to the southern tip of the Borough of Croydon. Virtually, of course. Our southern extremity is also rural, as the photo above attests. We’re on Ditches Road, a winding country track that heads down from Coulsdon towards…oh, we don’t know. Whatever’s south of London. Not much in the way of public transport in these parts, but you could take a hike from Coulsdon South rail, passing a forensic mental health unit, on the edge of something called Happy Valley and down past Sparklie Wood and ‘The Devil’s Den’. It’s all a bit strange round here. View in maps.
Our easterly peregrinations take us beyond the M25. That’s right, a small portion of Greater London lies outside its own Orbital. There aren’t many names on the A-Z at this point. In fact, page 79 of our Master Atlas is largely blank, save for the crimson declaration of ‘THURROCK’ and a cat’s cradle of farm tracks and dykes. The nearest place name is ‘Corner Farm’, although it looks like some of the outhouses of nearby Fen Farm might just trump it. We wonder if they get into arguments about who is the most easterly Londoner? If you wish to penetrate this hinterland, your nearest station is Ockendon. View in maps.
Our occidental champion is seemingly easy to pinpoint. It’s Junction 14 of the M25. But here we have a boundary dispute. Our A-Z sees the edge of London track the circumference of the roundabout, while Google Earth clearly shows the border passing through the centre of the junction and thus rendering the north-west portion of Horton Road as the true end point of London. There’s a huge Travelodge across the road where frontier pedants can argue it out. View in maps.
