Coventry Cathedral: Crypts found under ruins
Restoration workers have discovered nine crypts hidden under the ruins of Coventry's bombed cathedral.
Work has been taking place after a crack appeared in part of the 14th Century ruins, in September 2011.
It was already known there were two crypts, which were last open to the public in the 1970s.
Dr Jonathan Foyle, the chief executive of the World Monuments Fund, which is overseeing the work, said it was like finding a "subterranean wonderland".
