Kilchurn Castle is a cool old ruin on a rocky peninsula at the end of Loch Awe in Scotland. It was built back in the 15th century by the Campbells of Glenorchy, who were a big deal in the Highlands. Over time, they expanded the castle and their territory until they moved out in the 18th century. Now it's all crumbly and open to the public in the summer for exploring and checking out some awesome history vibes.
