Ancient tunnel unearthed
From the BBC:
Workmen have unearthed 1,000 years of history on a County Down building site. They have come upon an underground stone-built tunnel in Raholp, where our ancestors might have hidden from the Vikings or from warring neighbours. Archaeologist Ken Neill said that with chambers off from the main tunnel it was a quite complicated souterrain, and probably built by better off farmers. The opening that led to the tunnel - which leads into the hillside - will be sealed and the passage left alone.
