Wire Opera House, Opera house in Curitiba, Brazil

The Wire Opera House is a circular theatre of steel tubes and transparent polycarbonate panels, designed by Domingos Bongestabs, set in an artificial lake in Curitiba's Parque das Pedreiras. A walkway over the water leads to the auditorium, whose 2,400 wire-mesh seats face a reddish-brown stage floor backed by black curtains. White tubes arch above the stage, and two circular openings framed in white metal flank it.

Designed by architect Domingos Bongestabs, the theatre was assembled in 75 days and opened on 18 March 1992 on the site of a former rock quarry. Its inaugural performance was A Midsummer Night's Dream, directed by Cacá Rosset with the Teatro do Ornitorrinco, at the first Curitiba Theatre Festival. A maintenance and safety renovation was completed in mid-2006.

The name comes from the steel tubes and polycarbonate panels that make the building look like wire mesh. The opening play was A Midsummer Night's Dream, directed by Cacá Rosset with Teatro do Ornitorrinco, at the first Curitiba Theater Festival. In 1993 the venue hosted Curitiba's 300th-anniversary party and the launch of the CNT television network.

The building offers wheelchair accessible entrances, restrooms on multiple levels, and parking spaces near the entrance for visitors with mobility needs. The surrounding lake area provides space for walking and relaxing before or after a performance.

Metal tubes and steel cables form the main structural support, creating light patterns through the large glass panels during daylight hours. This design approach transforms the experience throughout the day as light and shadows shift continuously.
