Teatro Municipal Dix-Huit Rosado, Performance theater in Mossoró, Brazil.

The Teatro Municipal Dix-Huit Rosado is a performance theater in Mossoró featuring an Italian-style stage and contemporary layout. The building contains a main hall, first-floor boxes, and second-floor galleries arranged to accommodate different audience sightlines for performances.

The theater opened in 2003 as a result of a partnership between the city and PETROBRAS that funded its construction. It was built on the site of former railway tracks, replacing industrial infrastructure with a space for cultural activities.

The name honours Dix-Huit Rosado Maia, and the theatre sits on Avenida Rio Branco between the Estação das Artes Elizeu Ventania and the Memorial da Resistência, in the Corredor da Cultura de Mossoró. Its programme covers drama, comedy, musical, literary and dance recitals, folk dance, classical and contemporary ballet, conferences and assemblies. The Praça do Teatro in front is busy at night, especially with young people, and the city intends the house to be a living venue in daily Mossoró life.

The building sits along Rio Branco Avenue and is surrounded by a public plaza that becomes active in the evening. The location is easily accessible on foot and has entrance areas distributed across multiple levels to accommodate different visitors.

The theatre occupies the line of the old railway tracks: the Estação Ferroviária became the Estação das Artes Elizeu Ventania, which faces the theatre across Avenida Rio Branco. The Praça do Teatro in front is busy at night, when residents gather to talk and children play.
