AN EXQUISITE OPERA HOUSE BLENDING WITH THE NATURE

The Ópera de Arame, in Portuguese, or the Wire Opera House, in English, is a theatre house located in the city of Curitiba, the capital of the state of Paraná, in southern Brazil. It is one of the major tourist attractions of the city. Situated in the middle of an urban green park, Parque das Pedreiras, the Wire Opera House theatre is built out of steel tubes, totalling 360 tons of steel,  which gave it its name,  and sits 2,400 people.  It was built in 75 days on the site of a former rock quarry.
