Must-See Highlights on Castle Rock
Explore the crown jewels, medieval siege guns, royal apartments, and ancient sacred sanctuaries.
The Honours of Scotland & Crown Room
Forged in Scotland and Italy during the reigns of James IV and James V, the Honours comprise the Crown of Scotland (1540), the Sceptre (1494), and the Sword of State (1507). First used together at the coronation of nine-month-old Mary Queen of Scots in 1543, they survived centuries of war, the English Civil War (when they were hidden in Dunnottar Castle and buried in a church floor), and 111 years locked inside an oak chest in the castle until rediscovered by Sir Walter Scott in 1818.
The Great Hall
Completed in 1511 for King James IV, the Great Hall was the venue for grand royal banquets and state events. Its centerpiece is an awe-inspiring wooden hammerbeam roof with intricately carved corbels — the only surviving original medieval roof of its type in Scotland. The walls are adorned with an extensive collection of historic swords, pikes, polearms, and suits of armour.
The Royal Palace & Mary's Birthing Room
The Royal Palace was the official residence of the Stewart kings and queens. Above the entrance are the gilded initials 'MAH' for Mary Queen of Scots and her second husband Henry Stewart, Lord Darnley. Inside lies the tiny wood-panelled bedchamber where Mary gave birth on 19 June 1566 to Prince James, who became James VI of Scotland at 13 months old and later James I of England, uniting the crowns in 1603.
Mons Meg
Given to King James II in 1457 by Philip the Good, Duke of Burgundy, Mons Meg was one of the most powerful and feared super-guns of the Middle Ages. Weighing six tonnes with a 50cm bore, it could fire 150kg (330lb) stone cannonballs up to two miles (3.2 km). It saw action at the sieges of Roxburgh Castle, Norham Castle, and Dumbarton Castle before retiring to ceremonial salutes.
The One o'Clock Gun
Since 1861, a field gun has been fired from Mills Mount Battery at precisely 1:00 PM every day (except Sundays, Christmas Day, and Good Friday). Conceived by astronomer Charles Piazzi Smyth, it served as an audible time signal allowing sea captains in the Firth of Forth and Leith docks to synchronize their chronometers alongside the Nelson Monument time-ball on Calton Hill.
St Margaret's Chapel
Perched at the highest point of Castle Rock (130m above sea level), St Margaret's Chapel is Edinburgh's oldest standing building. Built around 1130 by King David I in honor of his mother, Queen Margaret (who died in the castle in 1093 and was canonized in 1250), it features pure Romanesque stone archways, decorative chevron carvings, and modern stained-glass windows depicting Saint Margaret, Saint Columba, and William Wallace.
Half Moon Battery & Argyle Battery
Constructed between 1573 and 1588 after the Lang Siege flattened David's Tower, the Half Moon Battery curves around the eastern flank of Castle Rock. Armed for over 200 years with 18-pounder bronze guns known as the 'Seven Sisters', it guarded the main entrance gates against incoming cannon fire while offering unmatched 180-degree vistas down the Royal Mile and Princes Street.
Prisons of War Vaults
Deep below the cobblestones of Crown Square, vast stone vaults were converted in 1757 into Scotland's most secure military lock-up. Over 60 years, thousands of French privateers, Spanish sailors, Dutch seamen, Irish rebels, and American prisoners taken during the War of Independence were held here in rows of canvas hammocks.
Scottish National War Memorial
Designed by Sir Robert Lorimer and opened in 1927 in what was once the North Barracks, this breathtaking neo-Gothic memorial commemorates the sacrifice of over 200,000 Scots in World War I, World War II, and subsequent global campaigns. Inside, the Hall of Honour contains magnificent stained glass by Douglas Strachan and the Rolls of Honour listing every fallen warrior.
National War Museum of Scotland
Located in the hospital quadrangle, the National War Museum tells the gripping story of Scottish forces at home and abroad through four centuries of warfare. Highlights include Robert Gibb's famous 1881 painting 'The Thin Red Line', highland broadswords, pipe banners, Victoria Crosses, and personal letters from frontline trenches.
