They groan’d aloud on London Stone / They groan’d aloud on Tyburns Brook

In 1803 William Blake returned to London, but was still facing a sedition trial in Sussex in early 1804. Finding himself living within view of the disused site of Tyburn and on a street where the River Tyburn was flowing directly underneath, he developed a new humanitarian symbol for the final phase of his spiritual polemic.

McDevitt's walk joins the course of the River Tyburn at Baker Street, finds the site of the lost medieval Tyburn Church, and tries to locate the mysterious 'Tyburn Brook'.  

2pm. £12. Meet outside Baker Street tube by the statue of Sherlock Holmes. Approx two and a half hours ending at Marble Arch tube. Please click here for tickets.
