Balladoole, at Chapel Hill in Arbory parish, is a multi-period archaeological site with evidence of activity from the Mesolithic era through the Viking Age. Its best-known discovery is an 11-metre clinker-built oak boat, dated to around 850-950 AD and typical of trading vessels used on Irish Sea routes, excavated in 1945 by German archaeologist Gerhard Bersu. The burial's position, some 350 metres uphill from the shore, suggests the person interred held high status, perhaps as a chieftain or merchant. Notably, the Viking-age boat burial was cut directly into and on top of earlier Christian graves, which some interpret as a deliberate act of desecration or dominance over the existing burial ground. Grave goods recovered include riding equipment, a gilded belt buckle, and an iron cauldron, many of which are now on display at the Manx Museum.
