Ah thanks for looking Newcastle Historian. The ornate building is quite interesting as I'm assuming the rest of the street would have looked similar to North Street and Saville Row. I'd found a written description of Lisle Street from 1828 which described it as a quiet street - so quiet it was forgotten about :lol:
I'm interested in what the 'proposed roads' are on the map.
Of the proposed (projected) streets on the map, the big one north of Lisle Street, appears to be Northumberland Road, and the one opposite old Eldon Square, appears to be Clayton Street, which until 1976 used to intersect with Blackett street at that point!
One other 'projected street' that is actually not shown on the map as such, would be Grey Street of course, running South from Blackett Street through Anderson Place. Also, Grainger Street is not yet shown (as 'projected') either.
