The Battery at Blackness Castle represents the fortress's artillery positions that commanded the Firth of Forth. These gun emplacements were part of the 16th-century modifications that transformed Blackness into one of Scotland's most advanced artillery fortifications. In Outlander, the battery serves as part of Fort William's defensive capabilities, showcasing British military dominance over Scottish waters. The strategic positioning allowed cannons to control shipping lanes and defend against naval attacks. The stone platforms and mounting points for artillery create an authentic backdrop for scenes depicting military surveillance and coastal defense. Historic records show these positions were actively used until the 19th century, adding authenticity to their portrayal as functional military installations.
