Arc Designs has created a cantilevered viewing platform, and walkway with a glazed floor, perched on one of the highest points of the Rock of Gibraltar. Named Skywalk, the viewing platform is built above an existing WWII military platform in the Upper Rock Nature Reserve that once served as a base for anti-aircraft Bofors guns. Arc Designs wrapped the existing stone platform with a 2.5-metre-wide glazed walkway and balustrade, which cantilever over the steeply dropping terrain. Steel stairs lead from the walkway up to the top of the original military platform, where the old octagonal concrete gun-base now serves as a seat for visitors to rest and gaze out towards the horizon. Located just a little further north of O’Hara’s Battery – the highest point on the Rock – the platform provides visitors with panoramic views both eastwards and westwards, with Europe and Africa, the Mediterranean Sea and Atlantic Ocean all in sight.
