If you’re not afraid of heights, you can now experience the famed Rock of Gibraltar in a whole new way. Gibraltar-based architecture firm Arc Designs has turned an old WWII military platform on the very top of the landmark into a gorgeous glass skywalk with stunning views of the Rock and the surrounding ocean. Located 340 meters above sea level, the Gibraltar Skywalk is comprised of four layers of glass and over 60,000 pounds of steel embedded into the rocky, steep terrain.

The glass-enclosed viewing area is built in the Upper Rock Nature Reserve, which contained a platform formerly used as an anti-aircraft base in WWII. The architects used the base as a starting point to extend a glazed walkway and balustrade over the rocky terrain.

Visitors can access the viewing platform via stairs or a glass elevator. Once on the walkway, they can enjoy east and westward views that look out over the Mediterranean Sea and Atlantic Ocean. In fact, according to Arc Designs, the extraordinary location drove the inspiration for the skywalk‘s design: “The design aspiration of this project was to afford the visitor with new and unrivaled views in all directions including over the rocky cliff-face below, while at the same time ensuring a subtle intervention, which did not detract from the natural and historic nature of this unique setting.”

Although the setting guarantees beautiful views, the perilous terrain did present quite a few challenges for the project. “Because vehicular access to this area is limited to very narrow and winding roads, the entire walkway structure had to be fabricated in smaller sections which could be transported and assembled together in-situ,” explain the architects.

To ensure that the glass skywalk was secure enough to withstand the visitor load, as well as the typical wind speeds – which can reach over 93 miles hour – the structure had to be embedded into the ground with multiple rock anchors. The entire project used a steel skeleton made up of 18 separate pieces. To build out the walkway, over 8,000 square feet of glass panels were installed.
