The city's first mayor was Felipe Nery de Aguiar,.
, or Teatro Prezewodowski, was built in 1883 and is one of the oldest in South America. It is constructed of masonry, with a façade 15 meters high—an important characteristic being the mobile auditorium, which, with a special mechanism, puts the main floor level with the stage, for balls and other types of events. The façade above the main entrance is decorated with an entrance porch with two Roman columns. Windows are on either side of this main entrance on the ground and first floor levels, and the first floor has two doors with fences of iron. The name of the Theater is a hommage to Estanislau Przewodowski, who fought in the Paraguayan War and was of Polish-descendant, and then leader of the Flotilla of the High, Uruguay River, unit of the Brazilian Navy, that was anchored here in the waters of the Uruguay River in Itaqui, during approximately 40 years. The Prezewodowski Theater is situated in front of the “Square Marshal Deodoro da Fonseca” and at the side of the Municipal City hall. During many years the theater had been the scene of stage plays of great international theatrical companies, that played in Brazil, in the axis Porto Alegre-São Paulo-Rio de Janeiro, and then going on to Buenos Aires and Montevideo. Due to the ease of the rivber travel, these European companies always played in Itaqui's Theater, giving to the city the nickname of “Small Paris.” Not only the foreign companies were attractions at the Theater, the biggest names of the Brazilian stage also have played in it, such as Prócopio Ferreira, Maria de La Costa, Nicete Bruno, Wilson Grey, Vicente Celestino and others famous artists from Teatro Municipal. With the advent of the Second World War, that prevented the coming of theatrical companies to Brazil, the Theater went into decay. The city administered the Theater until 1928, when the cinematographic entrepreneur Manoel Barbosa leased it monthly for R$350,000 réis. In 1931, it was leased to another entrepreneur, Mr. Eduardo Corbacho for the equivalent 10% of the incomes of the spectacles, with a minimum guarantee of R$300,000 réis. In 1933 the company Contursi & Cia leased it for the monthly value of R$600,000 réis, with the obligation to make it function at least four times per month, on condition that solo artists or the city’s artists played in it. In 1942, the building was sold at public auction, as a result of an action moved by a shareholder, who desired to recover the value of capital that she had subscribed. The building was bought in the auction by the city’s medic and politician Dr. Roque Degrazia, who later, for the same price that he had paid, sold it on to the city’s administration, which is still today the owner of its patrimony.
