Found the Liverpool archives useful for my project. I managed to gather information and images of the original streets of Liverpool:
Castle Street -
The Sanctuary Stone. Remnants of Medieval Liverpool excavated 60-70 years ago returned to its' place of discovery during road works in the area in 2010. Believed to be one of the marker for the fairs that would take place on the 'High Cross'.
Horse Mill on the New South corner of Brunswick Street and Castle Street (OS:SJ34229036)
Water Street -
The Tower on the North side lower end of Water Street (OS:SJ34009038). Was a residance before becoming a prison in the Napolianic war then demolished in 1819.

The White Cross - Junction of Chapel, High, Old HAll and Tithebarn Street (OS:SJ34129059) Named in 1554 and in 1653 a lantern was placed here like on the High Cross.
I have gathered more information through photographs which I will chart up and publish courtesy of the Liverpool Archives.
There are 77 photos from the archive, I will not be posting all of them but snippets.
