World War One "smoke mortars" are believed to be among a pile of ammunition recovered by builders working on a new heritage lottery building in King's Lynn earlier.
The area around the town hall was evacuated while bomb disposal experts removed the items, which included bullets.
The site will house the Stories of Lynn heritage lottery project which details the history of King's Lynn and is due to open later this year.
