For the second of the ancient sites on my doorstep:
2. The Mere Bank on the Croydon/Sutton border.
This
probable neolithic boundary earthwork is deffo my find of the 'lockdown'; always there (partly) in plain sight, yet hidden away by modern developments.
I stumbled on the feature while I was looking at the old 1880s OS map to explore the old Croydon airport site (before it was the airport) on
this excellent resource:
There it was going right across the airport site, just West of the Purley Way and intriguingly pretty much still marking the boundary between the Boroughs of Croydon & Sutton (& their Parliamentary constituencies):
I had a bit of a search and came across this really good study from the
London Archaeologist (downloadable PDF free) which included this tantalising 1932 aerial image of the then relatively new Croydon aerodrome/airport showing the faint trace of what was probably the flattened earthen, Mere Bank:
The Gower piece showed that the Mere Bank neolithic boundary feature stretched from Purley, up over the hill to the airport, all the way across it, through what is now the industrial estate, across Stafford Road and down (via Merebank lane) at least as far as the River Wandle itself, and probably well beyond towards/across Mitcham common:
Taking the more
platinumsage style interpretation, the earthwork could well have represented just a straightforward boundary marker between 2 (tribal?) areas of grazing etc. Or, ending as it does at the liminal space of a River 'cliff' on the Wandle, may have had a more ritualistic/ spiritual function? This sort of archaeological speculation fascinates me, especially given the archly suburban, developed nature of the terrain.
Anyway, what does the thing look like today?
Starting down at Purley, the earth work bank appears preserved in the space between Russell Hill and the footpath known under the old name of Coldharbour Lane:
Across the airport, for obvious reasons, the feature was flattened, but the modern-day borough boundary is marked by a raised death bund:
...and down at the Wandle the (terminal?) river cliff, possibly a place of spiritual significance/votive offerings ( ? ) is still clearly visible on the bridal path footpath along the river:
All under our feet!
Amazing.
