Estadio Ester Roa Rebolledo, stadium in Concepción, Chile

The Estadio Ester Roa Rebolledo is a football stadium in Concepción with a green rectangular pitch marked by white boundary and penalty-area lines, two goals with white posts and netting, and tiered seating under a white roof supported by white beams. A continuous blue banner reading "COPA AMÉRICA CHILE 2015" runs along the far stand above advertising boards for Claro, KIA Motors, Santander, MasterCard, LAN and TAM. After its 2015 renovation it seats 30,448.

The stadium opened on 16 September 1962, built under the government of Jorge Alessandri and managed by mayor Ester Roa Rebolledo, replacing an earlier wooden stadium on the same site. It was intended for the 1962 World Cup, but the 1960 earthquake led organisers to choose Rancagua instead. From 1973 it served as a detention centre during the military dictatorship; a memorial plaque was installed in 2004, removed during the 2013-2015 renovation and reinstalled in February 2016 at the Collao avenue entrance.

The stadium was renamed on 29 October 2010, after the death of Ester Roa Rebolledo, the mayor who had overseen its construction in the early 1960s. Fans still call it Collao or Estadio Regional. A plaque at the Collao avenue entrance honours political prisoners held here in 1973 and 1974; it was reinstalled in February 2016 after the renovation.

The stadium sits on Avenida Collao, and the memorial plaque to political prisoners is on one of the main pillars of that entrance. The 2013-2015 renovation kept much of the original structure while adding two tiers in the north and south corners and an administrative building. The Municipal Gym next door has served as a press room during major tournaments.

The stadium served as a detention and torture center during the military dictatorship, with prisoners held in locker rooms and interrogated under brutal conditions. Memorial plaques now commemorate the victims, making the site an important symbol of memory and human rights in the region.
