Renovation work has begun on a 14th Century building in Hereford.
Concrete blocks added to the structure of the Old Mayor's Parlour in Church Street in the 20th Century are being removed.
Wood fibre panels and lime render will be added between the original oak timbers using a system devised by English Heritage.
The building was saved from demolition 45 years ago with the help of the Ancient Monuments Society.
Colin Richards, from contractors CJR Heritage, said: "On a job like this you feel that you're actually touching history and almost working alongside the craftsmen who originally constructed the buildings 700 years ago."
The inside of the building features a fresco of Hereford castle and an ornate decorative plaster ceiling with the old Arms of Hereford dating from the 17th Century.
The building, which is being refurbished by the Church Street Charitable Trust, is now a gallery showing the work of local artists.
