It is located on Willis's Plateau at the northern end of the Upper Rock Nature Reserve, adjacent to Gun No.

Princess Amelia's Battery saw action during the Great Siege of Gibraltar, during which it sustained substantial damage.

Princess Amelia's Battery is in Gibraltar, the British Overseas Territory at the southern end of the Iberian Peninsula.

[4] The Willis's Batteries were constructed at the area of the former Reduto (English: Redoubt) de San Joachim, at an elevation of 440 feet above the isthmus.

Gilbard and Drinkwater Bethune, among others, related the story of a shot which found its way through an embrasure in Princess Amelia's Battery, hitting four of the soldiers, and amputating between three and seven lower extremities in the process, depending on the source.

[11][12][13] Two derelict buildings remain at the site of Princess Amelia's Battery, which is listed with the Gibraltar Heritage Trust.
