Whilst on The Knowledge you are expected to memorise every road within a 6-mile radius from the Charles I Statue in Trafalgar Square, clearly an impossible task.

To compound the problem, some roads with dissimilar spellings (Britten Street, SW3 and Britton Street, EC1) are similarly pronounced, others are pronounced differently from their spelling (Beauchamp Place, SW3).

But, by far the hardest to learn is the roads with identical names. The famous Abbey Road has a little brother in West Ham. The delightfully named Water Lane is to be found in four locations: E15, EC3, NW1, SE14, while unsurprisingly Gasholder Place, SE11 is uniquely named.

Royal male chauvinism abounds with four King Streets: E13, EC2, SW1, WC2, the latter two a stone’s throw apart, while Queen Street has only two examples: EC4, W1.

A scan of my Geographers’ A-Z gives me many other examples of identically named thoroughfares, these are just the ‘As’:
