Spyglass Battery, Artillery battery on Upper Rock, Gibraltar
Spyglass Battery is an artillery installation on Upper Rock featuring six guns aligned in a north-south direction. The structure includes ammunition magazines and shell storage facilities carved directly into the rock at both ends.
The battery was built between 1896 and 1899 as part of Gibraltar's defensive fortifications. It was equipped with six 10-inch guns designed for high-angle fire.
The military installation represents British engineering adaptations in Gibraltar, incorporating specialized gun positions with observation stations for target acquisition.
The installation included casemates and accommodations carved into the rock for operational personnel. Visitors should note that access involves climbing and navigating steep terrain on Upper Rock.
The battery connected two observation posts via an underground tunnel system for firing coordination. This hidden passage network allowed crews to move between positions without exposure.
