Built in 1905 in the style of the Paris Opera, the magnificent Municipal Theater is the home of Rio's opera, orchestra and ballet. Its lavish interior contains many beautiful details – including the stage curtain painted by Italian artist Eliseu Visconti that features portraits of 75 major figures from the arts, such as Carlos Gomes, Wagner and Rembrandt.
