The tunnel was constructed in 1777, supplemented by the parallel 'new' tunnel in 1827, and closed in 1914 due to subsidence and structural collapse. It hasn't even been officially surveyed in the last 50 years, though as it is not bricked up (to allow groundwater to drain out), I expect that 'urban explorers' do find their way in.
