Interim Protection for Giant's Causeway
Development proposals within 4 kilometres of the Giant's Causeway (Northern Ireland's only current World Heritage Site) will be subject to particular scrutiny pending formal identification of its setting.
There is currently only one World Heritage Site in Northern Ireland, the Giant's Causeway, the setting of which has not yet been formally identified by the Department. As an interim measure until such time as a new development plan is prepared for this area and this matter is addressed, development proposals within a 4 kilometre radius of the site will be subject to particular scrutiny by the Department.
