A museum in County Durham has received an £800,000 grant from English Heritage for urgent repairs to its roof.
The lead and slate roof is in need of extensive repairs
The Bowes Museum, Barnard Castle was placed the "at risk" register after leaks to the 130-year-old roof threatened its historic collection.
Specialist roofing contractors will carry out the work, which is expected to take a year to complete.
The grant is the largest amount ever to be awarded to a single building by English Heritage in the North East
Carol Pyrah, English Heritage regional director for the north east, said: "We are passionately committed to ensuring that future generations can enjoy England's historic assets.
"A particular priority for us is to work with our partners to ensure important historic buildings, such as the Bowes Museum, are successfully removed from our Register of Buildings at Risk."
Adrian Jenkins, director of the Bowes Museum said: "We have made significant improvements to the quality of the museum experience for visitors over the last few years, but have all the while been conscious of the need to quickly remove the worries associated with the leaking roof.
"The work will finally lay that concern to rest, and at the same time will be a catalyst for allowing improved access to some of the treasures stored in the upper floor rooms."
