This enables the ethereal structures to stand 21 metres high – taller than a six-storey building – and 30 metres long without any additional support.
The intricate portals were developed over the course of a three-year iterative design process in collaboration with an aircraft engineer and a manufacturer specializing in large format carbon composite.
Each portal features two vast doors, 21 metres high and 10.5 metres wide, that will be opened every morning of the 173 days of Expo 2020 in a symbolic act of welcoming the world. The portals lead to tree-filled arrival courtyards, also designed in collaboration with Khan – one in each of the three Expo 2020 districts: Opportunity, Mobility and Sustainability.
The structures are the first element to be fully revealed of Expo 2020’s Public Realm, which comprises more than six kilometres of walkable areas across the site.
Expo 2020 Dubai will open on October 20, 2020 and end on April 10, 2021.
