Orange Bastion, Military fortification in Gibraltar, United Kingdom.
Orange Bastion is a military fortification along the Line Wall Curtain with thick stone walls and gun platforms that once protected the harbor. The structure displays asymmetrical design with flanked sections and reinforced areas that evolved over multiple centuries.
British forces built this fortification in the 1700s on the site of an earlier Spanish defensive structure and named it after William of Orange. The structure received additional reinforcement with thicker walls and defensive works during the major siege that threatened Gibraltar.
The site reflects British military design through its distinctive architectural features and the way gun platforms were positioned for different eras. You can see how engineers adapted the structure to suit the weapons and tactics of their time.
After extensive restoration work, visitors can view two Victorian-era guns with protective shields mounted on the structure. The best way to explore the details is to walk around the fortification and observe the different layers of defense from various angles.
The structure was originally built with walls measuring roughly 12 feet (3.6 m) thick, which was a remarkable engineering achievement for its time. This extraordinary thickness allowed the fortification to withstand the heavy bombardment it endured during military conflicts.
