Balladoole, near to Castletown, is one of the Isle of Man’s most impressive ancient monuments.
Excavation has revealed a number of significant finds including prehistoric flints, Bronze Age burials, Iron Age earthworks and early Christian lintel graves.
A 10th century AD Viking boat burial which dates back to between 850AD and 950AD was discovered in 1945 by a German refugee and a team from the internment camps based on the Island.
The group were originally looking for an Iron Age hill fort but found the burial instead, lying within early Christian lintel graves, which contained a 36ft long Viking ship and the bodies of a man and woman.
An ancient Keeill chapel dating between 900AD and 1000AD and a Bronze Age grave dating to 10000 BC have also been discovered at the Balladoole site.
