Not all Bristolians will know that deep down underneath one of the city's most iconic structures are secret vaults. They were discovered by contractors working on Clifton Suspension Bridge 21 years ago.
The underground spaces are abutments that were part of the earliest construction on the site and were designed by engineer Isambard Kingdom Brunel, who died five years before the bridge's opening.
From April 1, visitors have the opportunity to explore the underground phenomenon that has remained undisturbed for 162 years until their chance discovery in 2002. A family-friendly Vaults Visits programme has been developed to run alongside the Visitor Centre’s popular in-depth Hard Hat Tour From April until October 31 this year.
