This is far from an original puzzle, but I thought it fit our current fortnightly challenge so well that it ought to be included here.

I saw it on the Futility Closet website, but it was originally created in 1830 by London printer Charles Ingrey.

Labyrinthus Londoninensis, or The Equestrian Perplexed

-- click the image for a more-detailed copy, or check out the zoomable version at the British Library --

The puzzle states:

Mending our Ways, our ways doth oft-times mar,
So thinks the Traveller by Horse or Car,
But he who scans with calm and patient skill
This "Labyrinthine Chart of London", will
One Track discover, open and unbarred,
That leads at length to famed St. Paul's Church Yard.


Suggested by the Stoppages occasioned by repairing the Streets. The object is to find a way from the Strand to St. Paul's, without crossing any of the Bars in the Streets supposed to be under repair.

I found more than one route due to a couple of loops:

The red path in this image appears to me to work. The blobby grey bits are my scribblings to help clarify some impassable or pointless routes.


  • $\begingroup$ A crash requiring reboot upon imgur upload meant your solution got here first, but basically the same. EDIT - judging by my comment post time to hypern you probably beat me by 10 seconds or so. $\endgroup$ Jul 20, 2016 at 16:17
  • $\begingroup$ I got the same path as this, couple minutes slower. $\endgroup$
