The strategic advantages of positioning the fortress on the rock’s summit become obvious when you reach the top. Castle Rock has more than just a castle, though. As you walk through the Entrance Gateway, you’ll see statues of Robert the Bruce and William Wallace. At the summit you’ll find the Scottish National War Memorial, St. Margaret's Chapel, and Mons Meg, a giant 15th-century siege gun.
Inside the castle complex, check out the Scottish Crown Jewels and the Stone of Destiny in the Royal Palace; in the Royal Apartments, visit the bedroom where Mary, Queen of Scots, birthed her son, James VI. As Edinburgh Castle is a popular attraction, buy your ticket in advance to save time and skip the entry line.
