Following on from another thread, this photo shows the Mynachdy estate above the railway line and the straight line of North Road. Above that are 'The Colonies'. The canal leading to Llandaff is obscured by trees.

Now, you've got your bearings, you can see the road over the railway leading to Patent Fuel works and a disused soap factory. I believe that Ferris Row of 27 homes is the curve of buildings just to the right of the stack, bottom left of the photo.

Probably best to copy, paste and enlarge image
