Belfast is hosting the Fleadh Cheoil, a week-long celebration of Irish music and culture expected to draw 800,000 visitors. The festival takes place in a city once divided by a "Ring of Steel" security barrier during the sectarian Troubles. The event is seen as a powerful symbol of Belfast's transformation in the decades since the conflict.
