Excavations reveal medieval trading center in Northern Ireland

Dr Philip MacDonald, leader of an archaeological excavation on Dunnyneil Island in Strangford Lough, Northern Ireland, believe he has found the "Holy Grail of retail" with the discovery of a 7th century trading emporium visited by merchants from around the world.

The island trading center, the equivalent of a "medieval mall," would offer furs, seal skin, slaves and Irish wolfhounds in exchange for luxury goods, such as wine, from as far away as Russia, Germany, Iceland and France. The barter led to the power and wealth of Dal Fiatach, the Kingdom of Ulster.
