The Lane was originally known as Willow Walk; it is thought to have acquired its present name after 1820, probably because of the presence of St Michael's Pant at its northern end. There is no sign of a complete lane on the 1774 map by Wilkins, but by 1827 it was fully developed, its two most important early buildings being the Bethel Chapel, built in 1804, and the Sion Chapel which was started in 1815. In 1866 the west side was much as we see it today, but during the present century the road was widened and, since the second world war the east side has been completely re-developed.
