The Estadio Único Madre de Ciudades is a stadium located in the city of Santiago del Estero in the homonymous province of Argentina. The stadium was inaugurated on March 4, 2021, before the 2019 Supercopa Argentina match contested by River Plate and Racing Club. President of Argentina Alberto Fernández attended the ceremony. The Estadio Único was expected to host some matches during the binational 2020 Copa América to be held in Argentina and Colombia. However, due to the COVID-19 pandemic, the tournament was re-scheduled to 2021 and eventually moved to Brazil. The stadium held its first international match on 3 June 2021, hosting the 2022 FIFA World Cup qualification match between Chile and Argentina. The stadium, the largest venue in the province, is owned and administrated by the provincial government and has a seating capacity of over 30,000 spectators. The stadium facilities include a restaurant, a museum, a game room, and parking lots. From Wikipedia
