Spitalfields was historically one of the poorest, most overcrowded and most crime-ridden districts in London: a parliamentary report of 1838 described this area as harbouring "an extremely immoral population; women of the lowest character, receivers of stolen goods, thieves and the most atrocious offenders". The southern section of Commercial Street was created in 1843–5 as part of a slum clearance programme, and to connect the Whitechapel thoroughfare with Spitalfields Market. It was laid out by the architect and planner Sir James Pennethorne along the approximate line of former Essex Street, Rose Lane and Red Lion Street, and entailed the demolition of some 250 sub-standard properties in Whitechapel and Spitalfields. The extension north from the market, to the Eastern Counties Railway's Bishopsgate terminus and to Shoreditch High Street, was made between 1849 and 1857 and opened in 1858. In both phases of development there was some initial difficulty in finding tenants for the building plots, and much of the street was not built up until the 1860s and 1870s. Only once Great Eastern Street had been laid out further north between 1872 and 1876, creating a continuation of the route towards Old Street and the City Road, did Commercial Street really begin to succeed as what had always been Pennethorne's aim, an artery allowing traffic to bypass the City of London. With the implementation of the London Congestion Zone in the 2000s, the road has once again seen continued activity from private and commercial vehicles seeking to avoid the 7am–6pm charge, and is a typical arterial route for emergency vehicles. Until the late twentieth century, the street was heavily dominated by the activities of Spitalfields wholesale fruit and vegetable market, and by outlets for the "rag trade". Since the mid-1970s, however, the area has been increasingly subject to a process of gradual gentrification. In part this reflects the changing character of Spitalfields more generally, but in Commercial Street in particular it was stimulated by the departure of the market in 1991, the arrival of a number of private residential developments, and the introduction of some modest traffic-calming measures. Many of the commercial units in the street are now occupied by fashionable clothing shops or restaurants.
Topography and architecture
The street's most significant features are Hawksmoor's grand Christ Church, on the corner of Fournier Street; and Spitalfields Market, the old fruit and vegetable market that is now bustling again after a long period of uncertainty. Both the market buildings and Christ Church are lucky survivors, as demolition has loomed for both of them at one point or another. '' in 1863, shortly before the building opened. The northern end of the street is dominated on its eastern side by the sprawling Exchange Building, an Art Deco former tobacco works, now residential. On the western side stands the former Commercial Street Police Station, also now a residential block named Burhan Uddin House. Just to its south, with a wing extending into Folgate Street, is the first tenement block of model dwellings to be erected by the Peabody Donation Fund for London's "industrious poor". The red-brick Jacobethan block was designed by H. A. Darbishire and opened in 1864, but was sold by the Trust in the late 1970s and is now a private residential block named The Cloisters. On the opposite corner of Fournier Street from Christ Church is the Ten Bells, a pub that is popularly associated with Jack the Ripper, as two of his female prostitute victims are supposed to have frequented the establishment. Many Ripper tours start out nearby. Although the pub has long been refurbished, it still retains some fine original tilework. Prostitution remained a feature of Commercial Street until recently. Dorset Street, which ran off Commercial Street to the west immediately south of Spitalfields Market, was dubbed the "worst street in London". Much of the southern section of the street is occupied by warehouse buildings of the 1860s. Wentworth Street runs off Commercial Street to the west. Immediately to the south of Wentworth Street lies the Holland Estate, a social housing estate with elements dating back to the 1920s, but which is dominated on its Commercial Street frontage by blocks of the late 1960s and early 1970s, including a 22-storey tower block, Denning Point. The estate is now managed by Eastend Homes, and in 2012 was undergoing a major programme of regeneration that would see the demolition and replacement of several of the blocks. To the south again is the 11-storey Ibis London Citybudget hotel, and beyond that, at the junction with Whitechapel High Street, the Relay Building, a 21-storey residential development. On the eastern side of Commercial Street stands Toynbee Hall, the university settlement founded in 1884.
