London's Lost Rivers: The Tyburn
The Tyburn is one the subterranean 'lost' rivers of London which, like the already visited River Fleet, Westbourne and Walbrook, empties into the Thames. Today's walk followed the route of the river from South Hampstead, through Regent's Park and Green Park, before meeting the Thames near Vauxhall Bridge in Pimlico.
The source of the Tyburn is at the Shepherd's Well near Fitzjohns Avenue and before it was culverted it ran down the hills before splitting into two distributaries, between St. James's Park and Buckingham Palace, creating Thorney Island on which Westminster Abbey was built.
The river is now enclosed by concrete, bricks, parks and roads, and is used for local sewers which connect to the wider London sewerage system.
The river gave the name to the former area of Tyburn, which was recorded in the Domesday Book and was a manor of Marylebone. Tyburn also gave its name to the predecessors of Oxford Street (Tyburn Road) and Park Lane (Tyburn Lane).
Distance: around 6 miles.
