Praça Mauá marks the beginning of Avenida Rio Branco avenue and also of the Port Region. From 1910 on, with the inauguration of Porto do Rio (“Rio’s Port”), began an important place to welcome ships that brought products and tourists to the city. Around the square there are important buildings, such as the Rio Art Museum (MAR) and the Museum of Tomorrow, as well as the A Noite building, the first skyscraper of the city, built in 1930. In the middle of the square, there’s the statue of Barão de Mauá, Irineu Evangelista de Souza, a great businessman from the time of the Empire.
