Archaeologists excavating Mingary Castle in west Ardnamurchan, Scotland have recovered a musket ball and canonball in the moat of the castle, speaking of an attack sometime in its past. Mingary is considered to be "the best preserved 13th-century castle in Scotland."
The ammunition, of yet undetermined age, consisted of an "extremely heavy" musket ball and four pieces of a cannonball with one side flattened. Both pieces were found in close proximity to each other. Jon Haylett, a historian who is documenting the progress of the excavation said: “The cannonball was found at the eastern end of the moat. It is probably in pieces because it hit the castle wall and fractured before falling into the moat where time and weathering have broken it into four pieces."
