A project to be jointly undertaken by Waterford and Antrim has been awarded 230,000 euro in funding.
It's part of a North-South initiative, involving 15 councils in the Republic and nine councils in the North.
The €230,000 is to fund a feasibility study into the re-purposing of specific derelict, vacant, or under-utilised sites in two communities in Waterford and two in Antrim.
Waterford City and County Council will be the lead local authority on the project, working with Mid and East Antrim Borough Councils.
They'll be working to find out if these sites can be regenerated for tourism, recreational, enterprise, and cultural purposes.
It's hoped the findings of the assessment can be developed into best practice models for town and village regeneration.
The Councils will work together to assess repurposing sites in Dunmore East and Portlaw and the Antrim villages of Glenarm and Portglenone.
More than €4.3 million has been allocated across the island of Ireland to develop these collaborative, cross-border investment projects in the next 12 months.
The scheme is being funded by the Shared Island Fund, managed by the Department of Housing, Local Government and Heritage.
