“As we intuit its previous use, like a projector our minds will conjure the past back into the space – we sense the ghostly movements of ‘absent presences’ across a factory floor or walking down a hotel corridor, feel the soft feet and flow of long-vanished revellers as we step across a disused ballroom, because they are the lines we all trace.

Whether you believe in autonomous ghosts and spirits or not, it is difficult not to at least think of the spectral echoes of those whose pasts we retrace as we move through the spaces we share. As such, paradoxically, it isn’t necessarily the presence of the spirits of place that haunt us, but their absence, and as long as we have the clues with which to construct them, ghosts will always be ready, just waiting to emerge.”
