Tyburn was a village in the county of Middlesex close to the current location of Marble Arch in present-day London. It took its name from the Tyburn or Teo Bourne 'boundary stream',[1] a tributary of the River Thames which is now completely covered over between its source and its outfall into the Thames. For many centuries, the name was synonymous with capital punishment, it having been the principal place for execution of London criminals and convicted traitors, including many religious martyrs.
