Why Is There A Dome On Top Of Kennington Station? | Londonist
... Approaching Kennington station at street level, the massive grey dome is easily overlooked, but glancing at the station from any sort of distance, or riding past it on a bus, it's hard to ignore. ... However, in the 1920s, these other stations were all modernised, with major changes to the outside of the stations including the removal of the domes. Work was done underground at Kennington, but little was done to the surface building, so the dome remained. ... To this day, Kennington station still has lifts, whereas they have been replaced by escalators in Stockwell and Oval. Elephant & Castle still has lifts, but many changes have been made to the original station, including the incorporation of the Bakerloo line and links to Elephant & Castle Shopping Centre, which opened in 1966. The dome has long since gone.
