Many space for presentations in Curitiba are tourist attractions in themselves. The Parque das Pedreiras ("Quarries Park"), for example, which includes the area that was once a stone quarry and has now been named the Pedreira Paulo Leminski, as well as a theater called the Ópera de Arame ("Wire Opera House"), has already become a tourist point. The Pedreira Paulo Leminski is an open area where events can be held for large audiences, for it has a capacity of up to 30,000 people. The Wire Opera House was built in a record-breaking period of 75 days to host the first edition of the "Festival de Teatro de Curitiba". Its metallic structures, which look like wires, have become an architectural mark in the city and nationwide.
