It takes aspiring London cabbies two to four years to acquire ‘The Knowledge’. Only if they know their way around the 25,000 streets in a 6-mile radius from Charing Cross (and along 320 main roads within Greater London) will they be licensed to drive one of London’s iconic black cabs. The London Taxicab Examination System is reputed to be the hardest of its kind in the world, and this speaks to the complexity of the British capital’s road grid.
That complexity, and the cabbies’ Knowledge, put passengers at the risk of being overcharged, the Victorians feared. Mid-19th century, even before the current Examination System was instituted (in 1865), a Mr John Leighton devised a system to prevent passengers from being taken for a proverbial as well as a literal ride. Leighton, a Fellow of the Society of Antiquaries, published a scheme to divide London in a number of hexagonals, specifically aimed at preventing overcharging by cab drivers.
“John Leighton suggested that the old borough boundaries should be altered to conform to a honeycomb pattern. Within a 5-mile radius of the General Post Office all the sprawling, differently sized boroughs were to become hexagonal-shaped areas, 2 miles across. There were 19 altogether with the City in the centre of the honeycomb. Each hexagonal borough would be identified by a letter, and the letter as well as a number would be painted or cut out of tin-plate to be visible by day and night on lampposts at every street corner.”
The proposal for a hexagonal London is described in London As It Might Have Been, a book by Felix Barber and Ralph Hyde, also detailing plans for a giant pyramid to house the remains five million dead Londoners, and a scheme to erect a structure in Wembley to dwarf the Eiffel Tower in Paris.
Leighton’s hexagonal plan obviously never came to fruition; it is strangely reminiscent of a proposal dating from 1790 by Jacques-Guillaume Thouret to divide France into completely rectangular departments (#159) and of the ideal, geometric city as envisioned by Sir Ebenezer Howard in 1898 (#234).
Of the two maps shown here (*), the one the left shows the Metropolitan Parliamentary Boroughs as Constituted Under the Act of 1855, centred on the City, and shown with their subdivisions (St Pancras, for example, is divided in N, S, E and W). The result is a veritable hodgepodge of miniscule fiefdoms. The map on the right presents a more regimented view of London, re-divided in 2-mile hexagon-shaped boroughs, centred around the City in three concentric circles.
Six boroughs in the first circle are numbered thus (clockwise from the top):
- 1 Islington
- 2 Bethnal Green
- 3 Southwark
- 4 Kennington
- 5 Westminster
- 6 St Pancras
Twelve boroughs in the second circle are numbered thus (clockwise from the top):
- 1a Hornsey
- 2a Hackney
- 3a Old Ford
- 4a Poplar
- 5a Deptford
- 6a Peckham
- 7a Brixton
- 8a Battersea
- 9a Chelsea
- 10a Marylebone
- 11a St John’s Wood
- 12a Kentish Town
Eighteen boroughs, unnumbered, are in the third circle (clockwise from the top):
- Tottenham
- Stamford Hill
- Leyton Essex
- Forest Gate
- West Ham
- Blackwall
- Greenwich
- Lewisham
- Forest Hill
- Norwood
- Balham
- Wandsworth
- Fulham
- Kensington
- Paddington
- Willesden
- Hampstead
- Highgate
Many thanks to Simon Austin for sending in this map, found on Kosmograd, a blog animated by an interest in, among other things, utopian architecture, disurbanism, cyberspace. The relevant post starts from this original hexagonal idea to produce a contemporary hexagonal map of London.
(*) a bit dark and hazy; any image of better quality is very welcome.


I know that Washington DC instituted a zonal system for cab fares in the city for this reason.

The “Eiffel Beater” in Wembley is quite a story. Watkin’s Tower, or what’s left of it, is actually *under* the current Wembley Stadium. When they tore down Old Wembley they lowered the level of the playing pitch before laying the new one, and the foundations of the tower were still there.
Comment by Paul Drye — October 18, 2009 @ 2:05 am
Oh, forgot to mention: the “?” in the third ring of boroughs is probably “Willesden”.
Comment by Paul Drye — October 18, 2009 @ 2:13 am
Hi Paul,
Willesden it is, thanks!
Comment by strangemaps — October 18, 2009 @ 2:25 am
There are, in a geometrically obvious kind of way, eighteen boroughs in the third circle, not nineteen.

London As It Might Have Been is a wonderful book, which I’ve been recommending as a source for alternate history for many years, but there was an unfortunate tendency to print the maps too small and/or too faint or too dark. Whoever did your scan has done a pretty good job of cleaning up the image, it’s as readable as it is in the book.
Comment by Marcus Rowland — October 18, 2009 @ 8:48 am
Born and raised in Strasbourg (F) one of the city’s worst borough was planned according to this theory of an homogeneous net: Hautepierre. Unfortunately I found no english website on the borough but there is the french wikipedia link : http://fr.wikipedia.org/wiki/Hautepierre
Look at it on google maps it’s impressive. Everyone knows about french cars burning ? You know some suburbian riot in 2005 and every year at new year’s eve… It began in this borough… Strasbourg’s citizen are so proud of it (lol). Anyway, the borough is still one of the most dangerous of the city… and you get lost very very easily on the too many winding roads.
Comment by Pier-Mael Anezo — October 18, 2009 @ 9:21 am
Seeing the map of the plan, I couldn’t help thinking of the (descriptive) Central Place Theory (http://en.wikipedia.org/wiki/Central_place_theory) by Christaller.

@ Nicola Larosa:
Must have counted Tottenham twice. Corrected, thanks!
@ Marcus Rowland:
Too bad about those maps. Sounds like a fascinating book nonetheless – I’ve put it on my wish list.
@ Pier-Mael Anezo:
Thanks for that link. The similarity with Hautepierre is eery – especially in light of its reputation. Maybe hexagonals are not the best model for urban landscaping…
@ lijn:
Thanks. Reminiscent of the cliometric theories mentioned in Eifelheim, an SF novel by Michael Flynn.

Well, I think that now London is actually divided in hexagonal zones, albei for other reasons: GSM cells are hexagonal.

Westminster City Libraries used to have several copies, not sure if they still do. The cheap edition (full sized but paperback) was remaindered a few years ago – I got several copies for friends etc, but unfortunately have none left now.
I’ll keep an eye open, it might just turn up somewhere.
A brief list of the other maps:
Four 1638 – 1665 versions of Whitehall as it would be with a vast Royal Palace there.
The City as it would have been if Wren’s plan for rationalizing the streets had been used.
Another plan for rationalizing the City’s streets post the Fire of London.
A plan for a palace in Hyde Park (proposed by supporters of the Jacobites and never built)
London with a completely straight triumphal way cleared between the above palace and St. Paul’s Cathedral. Unfortunately very faint.
A variant layout design for Regent’s Park
The “Great Metropolitan Station” linking all London’s main railway lines
Post WW2 plans for a new park in Southwark.
A 1796 plan to straighten out the Thames by cutting through the Isle of Dogs
There are also building plans, sketches, photos of models, etc. but I assume they’re outside your area of interest.
Comment by Marcus Rowland — October 18, 2009 @ 1:46 pm
You mention the plan to divide France into rectangles, and a lot of the states and counties in the western USA tend towards rectangular shapes. However, the hexagon is actually more rational, being the tilable shape with the largest number of sides, thus minimising the distances of all points from the centres of each area, which could be the administrative centre. I’ve often wondered whether such a plan had ever been attempted anywhere.

Comment by Chris Ronk — October 18, 2009 @ 4:45 pm
Actually there are good reasons to use rectangular/mostly rectangular shapes: They are really easy to describe precisely.
“The territory shall consist of the lands east of the River Foo from 27 degrees north to 37 degrees north and extending to 103 degrees west, excluding lands on the west bank of the River Bar.”

Of course, even if this had been done, London cabbies would still be “not goin’ sarf of the river, guvnor”.

I wonder what the GPS system has done to the need for the London Cabbie to have the “knowledge”.
Any news?
Comment by chris — October 19, 2009 @ 10:50 am
Actually, an article on London Cabbies (and GPS) was in the tab right next to this for me.
London cab drivers apparently have oversized hippocampuses because of “the Knowledge”. No word on how much they’re using GPS, but there are concerns that GPS might contribute to dementia. Bring on the real maps!

Always enjoy these Strange Maps, and no doubt the book of the site is good too. You might alsolike to check out “You Are Here: personal geographies and Other Maps of the Imagination” by Katharine Harmon, published by Princeton Architectural Press.
Fascinating collection of maps, beautifully produced.
(By the way I have no personal link to the publisher nor to the author. I just love the book.)

@Chris: I was in London last September. As usual, I always take the taxi, and I must say I have yet to encounter a cabbie that uses a GPS. Maybe they think their customers won’t like having to wait for them to enter the adress in the GPS and then wait still a bit longer for it to calculate the route?

London black cabbies are still as fab as ever – and they ignore GPS because they know all the shortcuts and jam-avoiding routes. They go south of the river now, too, @Roy!
I’m glad this plan didn’t get underway – one of the joys of London is its randomness and fluidity, its layers of history jostling against each other.

Comment by المطور العربي — October 19, 2009 @ 6:25 pm
GPS doesn’t work too well in London, especially not in the centre. The buildings are too close together and the signal gets a bit scrambled and it tends to jump around, thinking you’re on a different street altogether. This may improve, but I expect the cabbies will need their ‘knowledge’ for a while

I believe (unless they’ve changed things recently) that public transport in the Netherlands is arranged in hexagonal cells like this, which cover the entire country. Travel by bus or tram (not sure about trains) and you pay (n + 1)x for your journey where n is the number of cells you cross, ie 2x for journey within a single cell, and so on.

Me, for one. I was about to say the same thing as soon as I saw the hexagonal map. I don’t know what the resources might be, but I’d be inclined to start the Robber in the City.

Comment by Cubilone — October 31, 2009 @ 10:02 pm
I think the term London “road grid” implies a plan that never was. London is a city that grew from numerous villages, towns and other “places”. So there’s no “grid” and — most confusingly for a visitor — even when a street continues for quite a distance, its name may change every few hundered feet.
