Connecting Rotherhithe and Wapping, the Thames Tunnel was built between 1825 and 1843 by Marc Brunel and his son, the legendary Great Western railway engineer, Isambard Kingdom Brunel.
Hailed in its day as the eighth wonder of the world, it was the first tunnel in the world to be constructed under a navigable river and is now regarded as one of the greatest engineering feats of the 19th century.
Opened to the public for just two days this weekend, we were lucky enough to bag some tickets. Here’s a few photos from our trip.
