Clearing out the 'bookmarked stuff' on my computer, I came across this map;
Greenwood's Map of London 1827, which I'd forgotten about.
It is a very worthwhile
resource for anyone interested in London and it's History, so I thought I'd add a link here.
Unfortunately, the map doesn't cover Harringay, only reaching as far North on a line Camden Town, Caledonian Road and Dalston.
It is very important, as it depicts London a decade before the Railways reached the metropolis, clearly showing the locations of the stations and lines, which were mostly unbuilt land at that time.
The newly constructed Camden Road is shown; the beginning of the thoroughfare across fields from Camden Town to Holloway, which as Seven Sisters Road was further extended to Tottenham in 1833.
Of interest to me, the whole area around Victoria Station, a decade before Victoria had become Queen and thirty years before her name was given to the station and eventually the area surrounding it.
Great stuff for anyone, like me who often wonders why the London we know today, is the way that it is..
