John Nash's 1827 arch, moved to its present location in 1851, stands amid the traffic whirlpool where Bayswater Road segues into Oxford Street, at the top of Park Lane. Search the sidewalk on the traffic island opposite the cinema to find the stone plaque that marks (roughly) the place where the Tyburn Tree stood for four centuries, until 1783. This was London's central gallows, a huge wooden structure with hanging accommodations for 24. Cross over (or under—there are signs to help in the mazelike underpass) to the northeastern corner of Hyde Park to Speakers' Corner.
