Item 15 “the point from where all distances from London were calculated”. Don’t think so – it was one of about nine different points depending on destination. If you used the Barnet road you’d be measuring from there; but going to Essex it’d be from Whitechapel Church; to most of the northwest from Tyburn Turnpike; and so on. A little mistake but it makes one a bit twitchy about other facts.

Hopefully item 31 is just a typo in the post and not in the book as it seems unlikely that Zeppelins were bombing London in 1919 well after the armistice and in any case there weren’t any airship attacks on London after late 1917 anyway. Perhaps the Zeppelin Building in Farringdon Rd https://goo.gl/maps/eHw7Xj1diLo and also Bartholomew Close should have got a mention as they are on the map and were bombed as early as 1915

Item 10 – Somehow it seems more likely to me that Bowling Green Lane was named after bowling greens rather than bowling alleys which I think of as being indoor wood-floored places, especially as the Ogilby and Morgan map (1676) shows bowling greens there, and Vol 46 of the normally well-researched Survey of London mentions only bowling greens.

Item 3 – there are plenty of flag sites that say the sword on the City flag is the sword of St Paul (that’s the sword that martyred him not a sword he had). The City had a page that said that too, and specifically said that it couldn’t be a sword that killed Wat Tyler as the design pre-dated his death. Not on their site now, but the lovely internet archive has a copy http://web.archive.org/web/20040510112205/http://www.cityoflondon.gov.uk:80/leisure_heritage/libraries_archives_museums_galleries/clro/pdf/cityarms.PDF

Item 28 – I always think it’s polite to include a “reputedly” when repeating things that are most likely urban legends, and certainly not documented fact.
