Santos is a municipality in the São Paulo state of Brazil, founded in 1546 by the Portuguese nobleman Brás Cubas. It is partially located on the island of São Vicente, which harbors both the city of Santos and the city of São Vicente, and partially on the mainland. Santos has the biggest seaport in Latin America. Coffee exports from the Port of Santos gave rise to the city and mostly accounted for the wealth of the city at the turn of the 19th to the 20th century.
Lowry refers to the port in his novel Ultramarine; Popplereuter says "This time we made a trip to Sudamerika - Santos and Paraguay, San Francisco, Florianpolis - Port Allegre. We have been rolling around the world." (P.86).
