A new attraction has opened up high on the Rock of Gibraltar, with Star Wars actor Mark Hamill on-hand to launch the aptly-named Skywalk to the public.

Sitting 340m (103m) above sea level, the new attraction offers 360-degree views of the British overseas territory, with views spanning three countries and two continents. The new attraction links up with the existing Upper Rock Nature Reserve, Windsor Suspension Bridge and the Apes’ Den, which are connected by a series of walking trails.

A joint venture between Koala Construction and Bovis, the glass walkway is built on the foundations of an existing WWII base structure and is designed to withstand wind speeds of up to 150kmph. The Skywalk’s floor is made from four layers of treated glass, with the 42 panels able to hold up to 350 people without breaking. Extending out from the rock face, 6.7m (22ft), the 30,000kg steel structure is anchored by 70m (230ft) of rock.

“We were contracted by the Government of Gibraltar to carry out the design and build of the viewing platform on the former military site,” said Bovis Koala in a joint statement.

“The design provides 360-degree views, achieves a continuous route and flow around the lookout, and offers controlled opacity to accentuate the corner point with the most impressive views. The glass walkway is a floating element and avoids direct contact with the existing military platform.”

Hamill, who played Luke Skywalker in Star Wars, was accompanied by Stormtrooper dance outfit Boogie Storm, as he officially opened the new attraction. Cutting the ceremonial red ribbon with a lightsaber, Hamil declared that the “Force is strong” with the Skywalk.

“At the top of the Rock of Gibraltar the Skywalk will serve as a stunning attraction for years to come,” said Fabian Picardo, chief minister of Gibraltar.

“It is only fitting that Luke Skywalker’ himself, should take the first steps.”
