The Irish government has formally announced 15m funding for a new visitor centre at the Battle of the Boyne site.
There will be a visitor and exhibition centre, new walkways and a peace garden put in over the next three years, bringing total spending on the project to date to 30m.
Talks have also been held with experts from world battle sites like Gettysburg, Waterloo and Flanders.
“We can learn from their experience of developing these sites which, in a sense, stand as monuments to a bloody past that should never be repeated,” said Minister Dermot Ahern.
The site attracted 20,000 visitors last year.
