Edinburgh Dungeons are offering free entry to those who utter a 'secret phrase'.
On the first day of the launch of their new show, July 10, visitors can get in completely free by saying a simple sentence: "We're here to capture the castle."
Their summer show takes guests back to 1341, exploring Scotland's fight to take back Edinburgh Castle.

The interactive tour is packed with 'gags and gizmos', and tasks 'whoever dares' with recapturing the capital's castle and 'joining the rebellion'.
Simon Beattie, General Manager of The Edinburgh Dungeon, said: “We’re so excited to launch our new summer show. We thought what better way to celebrate the new experience, which takes people back to the period shortly after the Great Scottish Wars of Independence than giving them a freebie.
"Interestingly, latest figures suggest that Scots do want to remain as part of the United Kingdom, but it’s very close, with 46% supporting independence. So, although our new show implicates a revolt against English rule, it’s all light-hearted and fun in true Dungeons fashion.”
Capture the Castle runs from July 10 to August 31, and you can find out more here.
