Teatro Argentino de La Plata, Opera house in La Plata, Argentina.

Teatro Argentino is a modern building with brutalist architecture that houses a large concert hall with around 2,000 seats and a smaller hall with about 300 seats. The complex occupies an entire city block in the center of town.

The original theater built on this site in 1890 was designed in Renaissance style but was destroyed by fire in 1977. The current building was rebuilt from that loss and completed in 1999.

The theatre's name recalls the Sociedad Anónima Teatro Argentino, founded in 1885 to give the new city a stage. Its stable orchestra and chorus date from 1938, when they first appeared in Puccini's La Bohème, and the ballet company from 1946 under Giselle Bohn. The main hall is named after composer Alberto Ginastera, the smaller one after Astor Piazzolla.

The complex fills the block bounded by streets 9 and 10 and avenues 51 and 53, on La Plata's Monumental Axis of public buildings. The main entrance, with steps, metal handrails and glass doors, faces the lower glass front where the season's signage is mounted; posters and a small screen stand beside it. The Alberto Ginastera Hall seats 2,000 and the Ástor Piazzolla Hall 300, so check which hall a performance uses before setting out.

The three-tonne bronze chandelier with 400 bulbs in the Alberto Ginastera Hall is a replica of the one that hung in the 1890 Renaissance-style hall destroyed by fire in 1977. The new building's architects won the 1979 competition among 71 entries.
