The Traveling Taylors

Edinburgh Castle is one of Scotland’s most visited attractions, and for good reason. But beyond the crown jewels and cannon blasts, there are dozens of small, easily overlooked details that tell fascinating stories. If you’re planning a visit, here are 10 hidden details inside Edinburgh Castle you might miss—but definitely shouldn’t.

10 Hidden Details Inside Edinburgh Castle You Might Miss

1. The Tiny Door to the Dog Cemetery

Tucked near the Argyle Battery, a small iron gate leads to a pet cemetery for regimental mascots and officer’s dogs. It’s touching, historic, and easy to miss unless you look for the plaque.

2. A Bullet Hole from a Historic Siege

Near Foog’s Gate, there’s still visible damage from a 17th-century siege. Look closely at the stonework—it’s a quiet but powerful reminder of the castle’s turbulent past.

3. Carvings Inside St. Margaret’s Chapel

This tiny chapel is the oldest building in Edinburgh, but many visitors overlook the delicate carvings above the arched doorway and windows. Look up—they’re rich with medieval detail.

4. The Crown Room Ceiling

Everyone rushes to see the Scottish Crown Jewels, but few look up. The ceiling of the Crown Room is covered in vibrant, original woodwork and painted details.

5. The Stone Well Over 100 Feet Deep

In the Upper Ward, a simple grate covers a deep stone well once used to supply the garrison during sieges. It’s easy to walk past without realizing its strategic importance.

6. Latin Inscriptions on Cannons

Several of the cannons around the castle include Latin phrases and royal insignias. Look closely—they tell stories of battles, monarchs, and European connections.

7. The Queen Mary Room

This quiet corner is where Mary, Queen of Scots, gave birth to James VI. The room is simply furnished, but often passed by in favor of flashier exhibits. Its historical significance is massive.

8. Secret Military Tunnels

While not open to the public, you can spot the sealed-off entrances to tunnels that once allowed troops to move unseen. Guides sometimes point them out—so ask if you’re curious.

9. Prisoner of War Graffiti

In the vaults beneath the Great Hall, former POWs left carvings and drawings on the walls. Look for ships, names, and dates scratched into the stone—a haunting slice of history.

10. The Time Gun’s Hidden Setup

Everyone hears the 1 o’clock gun, but few realize the firing coordinates are synced with a clock in Calton Hill. It’s part of an old-time system to help ships in the harbor set their clocks.
