Some favorites from travels in the West Country of the UK:

Squeezeguts Alley (or Ope) in Truro, Cornwall

Jacob's Ladder, a steep, narrow staircase-cum-alley leading up from the Moor in Falmouth

Stippy Stappy, a similarly vertiginous lane in St. Agnes, Cornwall and, last but not least,

Peep Lane in Crediton, Devon (although it might have been even more at home in Coventry where the Lady Godiva did canter bare, clothed in only tresses fair...)
