Fancy a day outside London seeing an underground railway and an underground vault on the same day?
Deep under the streets of Bristol lies an abandoned underground railway that served a secret purpose in WW2 and is only now starting to occasionally open its doors to curious visitors.
Earlier this year, the first ever tours of the only-recently discovered vaults under Bristol's famous Clifton Suspension Bridge took place.
Experts had long thought the mighty stone foundations of the Clifton Suspension Bridge were as solid as the bedrock they stood upon. The experts were wrong.
