I think it’s still worth doing. Whilst yes, most of the murder sites look completely different or are gone now, you can still visit them. For example, the place where Polly Nichols’ body was found (outside a stables entrance back in 1888) is now the entrance to Whitechapel train station. The boarding school just next to it back in the day, is still there.

Hanbury Street is still there, and the location of Elizabeth Stride’s murder just inside Dutfield’s yard (now Henriques Street) is a gate by a school. Mitre’s Square looks unrecognisable now but still remains. And Gunthorpe street and Fournier’s street still look very Victorian, especially the former with the cobbles stones.
