A hospital in Suffolk, threatened with closure, has been Grade II* listed by English Heritage.
The Bartlet Hospital in Felixstowe was founded in the 1926
The Bartlet Hospital in Felixstowe was founded in the 1926 as a convalescent home from a bequest of £250,000 from Dr John Bartlet, a local surgeon.
It was built on the site of an early 19th century Martello Tower which was incorporated into the hospital design.
It was due to close this year due to health cutbacks but a final decision rest with the Department of Health.
Tony Calladine from English Heritage's designation team, said: "Listing Bartlet Hospital at grade II* recognises its outstanding architectural and historic significance.
"The early 19th century Martello tower has unique qualities including the rare survival of the dry moat and the hospital is also of high architectural quality.
"English Heritage looks forward to working with the Suffolk East Primary Care Trust in the future to advise on the future management of the site in light of its new protected status."
