Dig begins at crowning place of kings of Ulster near Cookstown
The mysteries hidden in a fort that was once the crowning place of the kings of Ulster are to be revealed in an archaeological dig.
Excavation work has started at the ancient Tullaghoge Fort, near Cookstown, as part of the first phase of redevelopment.
The Department of the Environment said the fort is one of Ireland's most important historical sites and was once the crowning place of the kings of Ulster, including Hugh O'Neill's inauguration in the 1590s.
Archaeological testing will take place at the bottom of the hill, to hopefully uncover information about the uses of the fort and its surrounding area.
The DoE said the testing would also help inform the best site for new visitor access to the monument, including a car park and interpretation area.
Environment Minister Mark H Durkan said: "This is a really exciting project at one of Northern Ireland's most important earthwork monuments that will result in a better understanding of the site."
