Coliseo Municipal Antonio Azurmendy Riveros, Indoor sports arena in Valdivia, Chile

The Coliseo Municipal Antonio Azurmendy Riveros is an indoor sports arena in the center of Valdivia, Chile, built primarily for basketball. It has tiered seating around a central court and can also be used for other sporting events and public gatherings.

The arena opened in 1966 to host an extraordinary men's world basketball championship, putting Valdivia on the international sports map for the first time. It went on to welcome other international tournaments in the following decades.

The arena's official name honours Antonio Azurmendy Riveros, a leading figure in Valdivian and Chilean basketball who was also mayor of the city from 1973 to 1976; the name was given in 1996. Before the Coliseo was built, local teams played at the Regimiento Caupolicán and then at the gymnasium of the Liceo Comercial on Avenida Ramón Picarte.

The arena is in Valdivia, Chile, and hosts basketball games and other events. The municipality states a capacity of 3,700, though sporting events have drawn 5,000 and music shows up to 6,500. Access depends on the event, so check the programme before travelling.

The arena hosted the 2007 FIBA AmeriCup Women's tournament, welcoming national teams from across the Americas to its court. That makes it one of the very few venues in provincial Chile to have staged a women's international tournament at that level.
