Canadian astronaut Chris Hadfield, currently the commander of the International Space Station, has an awesome Twitter feed in which he frequently posts amazing pictures of Earth as seen from the ISS. For example, he recently posted this picture of nighttime London as a memorial to Margaret Thatcher’s passing:
What’s striking about this picture is that you can clearly see the River Thames as it bisects London. What you can’t see in the picture, however, are the 21 other rivers in Greater London that flow into the Thames. And that’s because, in most cases, the rivers are now underground:
Here’s a brief summary of just a few of London’s “lost rivers”:
* * *
The largest, and perhaps most well-known, is the River Fleet. The river begins as two separate steams near Hampstead Heath, an ancient park which first entered the historical record in AD 986 when the gloriously (and accurately) named King Ethelred the Unready gave one of his servants land there. From Hampstead, the streams flow through Kentish Town to Camden Town, where they join. The river then flows underneath King’s Cross, which was previously known as Battle Bridge, because Roman historian Publius Cornelius Tacitus said the Romans fought legendary Iceni ruler Boudica at a bridge over the Fleet there. It then flows down Farringdon Road, and then Farringdon Street, before ending in the Thames underneath Blackfriars Bridge.
For centuries, the Fleet was a regular part of London life. It’s thought that the Romans built the world’s first tidal mill on the Fleet. The Anglo-Saxons, who called it fleot, meaning “tidal inlet”, dug several wells next to the river, from which Londoners got place names like Clerkenwell, Bagnigge Well and St. Bride’s Well. They also used the Fleet for shipping, and two short streets now named Newcastle Close and Old Seacoal Lane were originally wharves.

But by the 1200s, the river had become so polluted that the area became home to slums and prisons. Sir Christopher Wren advocated widening the river after the Great Fire of London (1666), but instead a man named Robert Hooke turned the river into a canal in the style of Venice in 1680. The upper part of Hooke’s canal was never popular, so in 1736 the area was covered up and a market built over it. The market survived until 1829, by which point it was so decrepit that it was knocked down and modern Farringdon Road was built in its stead. And the lower part of the river – already mostly covered by bridges and buildings – was built over in 1769 as part of the construction of Blackfriars Bridge.

with deeper sable blots the silver flood– Alexander Pope, 1728
The most famous part of the Fleet is probably the street named after it. For centuries, Fleet Street was home to most of London’s newspapers, and although most have since moved away, “Fleet Street” is still synonymous with the British media, in the same way that “Madison Avenue” in synonymous with American advertising.
The current Mayor of London, Boris Johnson, wants to uncover the Fleet as part of a “beautification plan” for the city, although the government agency tasked with the project is unsure it can be done.
