"Overlooking the city and capping Castle Rock, Edinburgh Castle looms over Scotland’s capital. Inside the ticket-only affair, you’ll see the Crown Jewels, the Stone of Destiny, and room after majestic room befitting of Scotland’s former royal family. Don’t miss the quiet calm of Saint Margaret’s Chapel, built in 1130, the oldest building in Edinburgh, or the National War Museum, also onsite. Visit the castle earlier in the day rather than later, when it can get crowded, but stick around until 1 p.m. if you can, when a gun is shot into the sky. And if you don’t want to pay the steep £18.50 entry fee (about $24), walk up the Royal Mile to the top and you'll still get to see the castle up close. The scenic views over Edinburgh and the mountains beyond come free of charge." - Freya Herring
