BBC: "Bletchley Park enigma code huts prepare for restoration"

'I shall say this only once'

"Seventy years ago, smoke would have hung in the air from the cigars and cigarettes smoked by the assorted workers and from the fires that were lit to keep the buildings warm.

Now there are drips from pipes falling into large holes in the floor.

Whilst other parts of Bletchley Park have been restored, many of the key buildings - like Huts 3 and 6 - have been left to ruin, but not for much longer as a major refurbishment project will get under way in the coming days."
