Steve; I couldn't work out that Clive Road bit either! Couldn't remember where it was, off hand. And I had quite enough on my mind without bothering about it.
Barrack Row, I worked out, was just to the south side of St Tom's. It ran down to where all the walls and stuff remain today. I'm not too good on Old Portsmouth ~ never liked the place, to be honest with ye. So, I can't remember enough to try and visualise where it would've been. I see the roof tops in that water painting though.
Steve, as an aside; Whet ye reckon on some of those images of " The old road into Portsmouth "?

Makes ye think, when ye realise that Pompey was once the size of a football pitch and ye entered it over a bridge and under a tunnel!
