Fully guided tour of the Clifton Suspension Bridge’s Underground Vaults. Minimum age 7+; recommended for adults. Private group tours are available by arrangement.
When construction of the Clifton Suspension Bridge began in 1831, the eyes of the world were on 23-year-old Isambard Kingdom Brunel and his bold plan to build the highest and longest bridge in the world. Many of the bridge’s secrets, like the vaulted chambers sealed inside the abutment, were lost when Brunel died.
Join our knowledgeable volunteer guides on a one-hour historical tour through two of Brunel’s twelve vaulted chambers. The tour will begin on the abutment above, then once you’ve descended the ladder your guide will share some of the most interesting features and explain why it took until 2002 for the Clifton Suspension Bridge vaults to be rediscovered.
- “Really interesting and informative tour, the guides were passionate about the subject and happy also to answer questions. Would recommend.”
- “Loved the passion of our guide. Clearly knowledgeable and had a few quirky anecdotes to boot.”
- “I totally loved it. Fascinating knowing how it was built and what was below. Very impressive.”
