The Tyburn is a stream in London, which runs underground from South Hampstead through St. James's Park to meet the River Thames at Pimlico near Vauxhall Bridge. Before it was covered over, the Tyburn arose from the confluence of two tributary streams from the hills of Hampstead. At what is now St. James's Park, it split into three branches, two of which formed Thorney Island on which Westminster Abbey was built. The Tyburn is now completely enclosed and flows through underground conduits for its entire length, including one underneath Buckingham Palace. Marylebone Lane (W1) follows the course of the Tyburn on what was its left bank through Marylebone village. From its source at the Shepherd's Well near Fitzjohns Avenue in Hampstead it flowed south through Swiss Cottage down to Regent's Park. In the park the Tyburn is carried in an aqueduct over the Regent's Canal.
