1: St. Catherine's HillNorth is at the top. The area covered by the image is roughly five square kilometers (two square miles). Winchester lies immediately to the north. The large building to the west of St. Catherine's Hill is the St. Cross Hospital, the terminus of the "Keats Walk". If you park in the lay-by next to the viaduct, it takes no more than an hour or two to complete any number of pleasant circular walks, even at the annoying stop-start pace we might call a "photographer's dawdle". Note the handy pedestrian bridge over the motorway between the hill and Twyford Down, and the tunnel beneath the motorway between the viaduct and the southern stretch of the Itchen. There is nowhere that cannot be connected to anywhere else, on either side of the road.

Obviously, satellite imagery tends to flatten out topography. For example, you get little sense of the depth of the valley between St. Catherine's Hill and the motorway, with its very steep rise up to the left-hand side of the cliff-like cutting. Also, from space Twyford Down looks like a flat field; it's hard to imagine the exhilarating sense of elevation you experience when walking on that rolling high ground. What you do see, however, is the way everything diverges and re-converges as it flows around the hill, like a rock in a stream. Or perhaps like a gigantic green eye, gazing back at the satellite.
In fact, the main road into Winchester used to run along the west flank of the hill, tight alongside both the canal and the old railway line that crossed the river on the viaduct. The only way to really understand how entangled it all once was is to use a very large-scale pre-War Ordnance Survey map. Or, better still, an online service like that provided by the National Library of Scotland, which enables you to view and compare OS maps of different scales and vintages. A good map makes all the difference: is there anything more intriguing than seeing words in close proximity on a map like "Plague Pits", "Ancient Fields", "Roman Road", and "Earthworks"? Not to mention "Sludge Beds", or "Sewage Farm"?
