The ancient highway from Dulwich to London, formerly (from at least 1335 until at least 1788) called Aspole or Ashpole Lane. Its more modern name ‘is derived from the old signpost on Denmark Hill which for some reason or another was painted red.’ At its southern end was formerly the Crooked Billet, later known successively as the King’s Head and the White Hart, which was demolished in 1902. North Dulwich Railway Station, originally serving the London & Sutton line, dates from 1866.
