The monument was inaugurated in the first decade of the 1900s to commemorate the opening of the Amazon River ports for foreign trade in 1866.

The monument displays the date of November 15, 1889, which commemorates the proclamation of the Republic of Brazil, and the name of José Cardoso Ramalho Júnior, at that time Governor of Amazonas State.

The main figure is composed by the sculpture of a woman - representing the Amazon - with a torch in the right hand, while the left hand rests on the shoulder of the god Mercury - Roman deity that symbolizes Commerce - placed on the lower plane.
