Today In History with The Retrospectors The Tunnel Under The Thames
Marc Brunel’s visionary under-water tunnel from Rotherhithe to Wapping finally opened to the public on 25th March, 1843. It had taken 18 years to build, and was massively over-budget, but was the first tunnel successfully created under a navigable river anywhere in the world.
Its construction had cost lives, caused controversy and changed the way tunnels would be built forever. But it soon became notorious as a gangway frequented by pickpockets and prostitutes.
In this episode, Arion, Rebecca and Olly explain why Brunel had to build a vertical tunnel before embarking upon his horizontal one; tot up its takings as an enormously popular tourist attraction; and explain how the injuries sustained by Isambard Kingdom Brunel during its construction lead directly to his even more famous architectural masterpieces…
