The Mary Terán de Weiss Stadium (Spanish: Estadio Mary Terán de Weiss), commonly known as Parque Roca, is a newly constructed multipurpose stadium, in Buenos Aires, Argentina. It is located at Avenida Coronel Roca and Avenida Escalada in the Villa Soldati neighborhood.
The new stadium has a capacity of 14,510 spectators. The first phase of construction cost 11.5 million Argentine pesos (approximately US$3.71 million). Former Buenos Aires mayor Jorge Telerman officially opened the stadium on September 19, 2006. The first official event to take place in the stadium was a semifinal of the 2006 Davis Cup, between Argentina and Australia, on September 22-24, with the Argentine team winning, 5-0.
The stadium has four main spectator areas: court-level boxes, lower and upper grandstand decks, and upper enclosed boxes. Below the grandstands are locker rooms, a large gymnasium, and offices. In future stages (beginning in 2007), a permanent facade and retractable roof will be built. When finished, it will be the largest-capacity enclosed stadium in Buenos Aires. The stadium will be able to host many events besides tennis, including basketball, volleyball, and artistic and cultural fairs.
