Historic street lamps originally invented to burn off dangerous sewer gas are being restored in Sheffield.
JE Webb's cast iron Sewer Gas Destructor Lamps were designed to burn methane and other stagnant gases which regularly accumulated in urban Victorian sewers.
They were erected all around the country between 1914 and 1935. Sheffield once had more than 80 of the lamps and now has 25, 20 of which are Grade II listed.
Residents began campaigning for the lamps to be restored when the city council's replacement of every lamppost began, as part of the 25-year Streets Ahead road improvement programme.
Some lamps, now more than 100-years-old, have been vandalised or have lost parts over time. But they will now get new lanterns and arms, thanks to a scheme by Sheffield Council and Historic England. The lamps are situated mainly in hilly areas such as Crookes, Nether Edge, Meersbrook and Walkley.
Councillor Bryan Lodge said: "The lamps provide a nostalgic reminder of days gone by and remain lasting landmarks of Sheffield's celebrated heritage."
The work is due to be finished by December.
