It may not have the grandeur of some of East Anglia's other landmarks - but campaigners are fighting to preserve Norwich's Victorian gas holder.
The structure dates back to 1880 but it was disconnected from the gas network in 2009.
The National Grid is now seeking permission from the city council to dismantle it along with an underground one nearby.
Civil watchdog The Norwich Society say the whole area is part of Norwich's industrial heritage - and that the gas holder should be kept.
Conservation officers at Norwich City Council also say they can't support the demolition, recognising that the gas holder is a "significant element of the aesthetic associated with the city skyline".
