Cannon firing at Edinburgh Castle
The One O’Clock Gun at Edinburgh Castle: A Historic Tradition Explained
For over 160 years, the thunderous boom of the One O’Clock Gun has echoed across Edinburgh, captivating visitors and locals alike. Fired daily (except Sundays) from Edinburgh Castle’s Mills Mount Battery, this iconic tradition combines maritime history, military precision, and Scottish heritage. In this guide, we delve into the history of the cannon firing, why it happens, and how you can witness it firsthand.
History of the One O’Clock Gun
Origins in Timekeeping
- 1861 Start: The One O’Clock Gun was first fired on June 7, 1861, as part of a time-signaling system for ships docked in the Firth of Forth.
- Synchronized with the Ball: Ships used the gun’s boom to synchronize maritime chronometers (clocks) with the time ball atop Edinburgh’s Nelson Monument, which dropped at 1 PM daily. Accurate timekeeping was critical for navigation before GPS.
Why 1 PM?
Edinburgh’s location meant noon (12 PM) wasn’t optimal due to potential fog or low visibility. By firing at 1 PM, the time ball’s earlier drop ensured sailors had a visual cue even if weather obscured the gun smoke.
How the Tradition Works Today
- The Cannon: A modern L118 Light Gun replaced the original muzzle-loader in 2002, but historic cannons like the 19th-century M1857 64-pounder are still displayed at the castle.
- Firing Process:
- A Scottish soldier from the 105th Regiment Royal Artillery fires the gun precisely at 1 PM GMT/BST.
- The event is preceded by raising a red flag 5 minutes prior (historically warning ships to prepare). A second “time check” flag appears at 12:55 PM.
- No Real Ammo: A blank charge creates the signature sound without firing projectiles.
Fun Fact: The gun hasn’t missed a scheduled firing since World War II!
