The lease for Martello Tower, which has housed Seaford Museum since 1979, has been renewed and finalised.
Seaford Museum and Heritage Society now has the security of a ten year, rent-free lease.
Chairman and secretary of Seaford Museum and Heritage Society, Kay Turvey and Mike Wright met Mayor of Seaford, Cllr Mark Brown, at the Martello Tower to confirm the signing of the lease.
The society is undertaking a project to improve access to the museum in order to enable all residents and visitors to the town to be able to gain entry to the museum.
A spokesman for Seaford Town Council, said: “The tower is an iconic attraction of the town and is vital to preserve the history and heritage of the town and local area. Now that the new ten year lease is in place this will enable the society to apply for further funding towards the project.
“The society has also recently been successful in registering as a charity limited by guarantee, which opens up their opportunities for seeking support with the accessibility project.
“Seaford Town Council is committed to helping secure the future of the museum and society where it can and apologises sincerely for the delays that have been experienced with getting the new lease finalised. The council is looking forward to working in partnership with the society in the future and ensuring that the needs of the community and town are met.”
