Vietnam plan 135000-seat Trong Dong Stadium in Hanoi

Vietnam is planning what would become the world’s largest football stadium under a new development blueprint in southern Hanoi.The proposed Trong Dong Stadium is designed for a capacity of 135,000, which would place it above existing and planned mega-venues in the global stadium rankings. The project has been presented as a football-specific ground, rather than a multi-purpose arena with an athletics track to help Vietnam compete for major international events.Concept plans for the stadium show a design rooted in Vietnamese cultural symbolism, with architecture inspired by Đông Sơn bronze drums and exterior detailing intended to reference traditional motifs. The stadium is planned as the centrepiece of a much wider mixed-use scheme branded Olympic Sports City, with a broader build-out that includes sporting venues and major supporting infrastructure.Planning documents and design reporting around the scheme describe advanced stadium features including a retractable roof and a retractable pitch system. The pitch mechanism has been presented as a way to protect the playing surface and accelerate turnover for different event formats, with a goal of swapping or retracting the turf within hours.The stadium is set within a large-scale urban development footprint, with the sports infrastructure forming only one element of a wider residential and commercial district. Plans also reference additional arenas and facilities alongside transport links designed to support major-event staging, with the project positioned as a long-term investment in the capital’s international sporting profile.The proposed schedule targets completion of the stadium by August 2028, with the wider Olympic Sports City development projected to continue into the mid-2030s. If delivered as planned, the project would create a new benchmark for football stadium capacity in Asia and globally, while underlining Vietnam’s ambition to host major international events in the future.
