From the Wikipedia page on the A215 
At its northernmost point at Elephant & Castle in Newington, the A215 begins as Walworth Road, which runs between Elephant and Castle and Camberwell Road. It runs through Walworth and is the major shopping street of the area. East Street Market is especially busy on Fridays, Saturdays and Sundays. Other attractions include the Cuming Museum, Newington Reference Library and John Smith House, a former Labour Party headquarters which is now used by the local education authority.
Charles Babbage, the Victorian mathematician and computer pioneer, was probably born at 44 Crosby Row, now Larcom Street, Walworth Road on 26 December 1791. A commemorative blue plaque is displayed on the Sexual Health Clinic at the junction of Larcom Street and Walworth Road.
Just off the Walworth Road was Walworth Road railway station on the London, Chatham and Dover Railway that was opened in 1863 and shut in 1916 due to wartime constraints.
