Historic England's annual health check of the UK's special and vulnerable historic places adds 328 sites
The world's oldest gasholder, an early Neolithic tomb and a London church linked to Charles Dickens are among historic sites on a new list of heritage considered to be at risk in England.
Gasholder No 2, at Fulham gasworks in London, was built in 1830 in the pioneering days of the gas industry and is the last standing example of its kind. Groundbreaking in its day, and twice the size of most gasholders at that time, it was thought to be the largest in the world. However, the Grade II* structure, including handmade wrought-iron work, is deteriorating – largely due to vegetation – leading to its inclusion on the register of at-risk sites.
