Dig to explore medieval town and plantation in Northern Ireland

Experts in Antrim County, Northern Ireland, are intrigued by evidence of a "lost" medieval town beneath a plantation-era Gaelic Scottish settlement and a 16th century castle. The evidence consists of a metal buckle and a silver groat, both dating to the 1550s.

The castle was built by Irish chieftains and seized by the Scots in 1550, but the plantation settlement was populated a century later by the Gaelic Scots. "The archaeology of the original 17th Century town is exceptionally well-preserved", dig leader Andrew Gault said, "We've effectively got a pristine plantation-era settlement here." The medieval artifacts were also found on the site.

The BBC plans to produce a program about the dig.
