the opera house is the major cultural heritage of the amazonas. it was inaugurated in 1896 during the rubber boom. in spite of the predominance of neoclassic elements, other styles were used, so the architecture is eclectic, with materials brought from europe as well as artists like domenico de angelis, giovanni capranesi and crispim do amaral. preserved as a national heritage since 1965, today, with more than 100 years, it has room for 681 people including balconies and three floors of boxes. after the restauration made by the state government in 1990, the theater rescued its splendor, with performances of famous operas, national and international musicians.
