WATCH: Game of Thrones gives Northern Ireland a tourism boost

BELFAST, United Kingdom — The week the final season of Game of Thrones premieres, an exhibition opens in Belfast celebrating its costumes, set pieces and Northern Irish filming locations.

The chief executive of Tourism Northern Ireland, John McGrillen, says the TV series has "driven up" the number of visitors coming to the country.

"We estimate that about one in six people who come here to Northern Ireland come to visit Game of Thrones set," McGrillen said.
