There's something eternally creepy about derelict spaces.
Maybe it's the fact that you know they were once busy and full of life, maybe it's the little bits of life left behind, maybe it's the fact that you never really know who's hiding in them, we're not sure.
What we are sure of however, is that they're always fascinating to explore.

From the empty tunnels, to the faded posters, take a walk through forgotten London....

The creepiest corridor...
Old signal staircase
This used to be full of commuters
Back before LED screens were a thing
This train has been sat in the station for over a decade
