In the center of Praça São Sebastião (Saint Sebastian Square) is the Opening of the Ports Monument. As the name suggests, Monumento à Abertura dos Portos was erected to celebrate the start of foreign trade in Manaus in 1866. At the base of this granite and Carrara marble commemoration are four ship prows. They represent Europe, Asia, America and Africa. On top is Mercury, the Roman god of commerce and financial gain. In the background is Teatro Amazonas. The dome above the opera house is decorated with 36,000 ceramic titles portraying the colors of Brazil’s flag.
