It's understood that it may show the proposals within the next two weeks to Moyle Council, which owns the ground that it will sit on.

The original visitors centre was destroyed by fire in 2000.

Since then, there has been an ongoing debate over what should replace it and by whom it should be built and owned.

At one stage, Moyle Council even considered selling the land.

But eventually a local developer, Seymour Sweeney, put forward a proposal to develop a multi-million pound centre at the World Heritage Site - plans which Environment Minister Arlene Foster said she was "minded" to accept.

However, last year, Moyle District Council suddenly agreed to lease the site to the National Trust. Following this, the minister did an about-turn and rejected Mr Sweeney's proposals. This left the door open to the National Trust to put forward the plans they've been developing for more than a year.
