RAF Davidstow Moor, Cornwall

The buildings that remain are low stone structures, roofless now or nearly. The corrugated metal doors on the larger ones have corroded into shapes that no longer close. Inside, the floors are concrete and rubble and whatever people have been bringing up here for the past eight decades: metal cans, clothing, wood. There's a basement level in one structure — a step down into a space with stone walls and a collection of wet debris that no one has touched in years. Everything in the interior is either corroded or colonised by damp.

The graffiti is blue. Someone — several someones, over time — has worked through these walls in the same colour, names and tags on stone that was built for wartime operations. The style shifts from panel to panel but the colour is consistent. Whether that's intention or coincidence in the available spray paint, I don't know.

Outside, five sheep were grazing in front of a black stone hangar. Not near it — directly in front of it, as if positioned. The hangar is long and intact enough to still read as a hangar, which makes the sheep in front of it look stranger than they would elsewhere.

Across the site a tall metal transmission tower stands where it has no obvious business standing. The concrete perimeter roads that once served the runways are still there, cracking at the edges, leading to structures that now have sky for a ceiling and mud for a floor.
