The Guzmán Marcos house, with art nouveau style, is a work by Francisco Maccaferri in the first decades of the twentieth century (1927-1929). The house belonged to married couple Walter Guzmán Aspiazu (Hamburg 1896 – 1981) and Maria Violeta Mercedes Marcos Ycaza (Guayaquil 1905 – 2002), who were known cacao farmers in the area.
Between 1870 and 1920 Ecuador was the first producer and cacao exporter in the world, and the cacao storages were located at the banks of Guayas River.
