Eilean Donan Castle as it appears today
Stonemasons working to weatherproof the walls of Eilean Donan castle, reduced to ruins during a Jacobite rebellion in 1719, have uncovered a vivid reminder of the building’s demise: 2 iron cannonballs embedded in the masonry, some 30 feet above the ground.
Measuring 7” in diameter, the cannonballs were revealed during a project to replace the protective lime and concrete coating applied to the castle in the 1950s. While similar objects have been recovered from the sea and shore surrounding Eilean Donan, these are the first to be found still stuck in their target.
When the commanding officer realised cannon fire would be ineffective, he ordered the castle to be taken by a landing party
"Three warships were dispatched to deal with the uprising, bombarding the castle with cannon fire", said castle keeper David Win. "Eilean Donan's walls were 14 feet thick in places. When the commanding officer realised cannon fire would be ineffective he ordered the castle to be taken by a landing party. After capturing the castle they fired the gunpowder store to destroy Eilean Donan."
When reconstruction began in 1912, the upstanding remains were incorporated - hence the reason we are still able to discover artifacts like the cannonballs.
