Recent work in Melbourne, including the papers in this volume, has shed new light on the archaeology of this major nineteenth-century urban center. But how does Melbourne compare to other important contemporary cities, particularly those outside the British Empire? This paper compares “Marvellous Melbourne” against the “Paris of South America,” Buenos Aires, with a focus on exploring consumer behavior and transnational trade. Two case studies are considered, Casselden Place (Melbourne) and La Casa Peña (Buenos Aires) and while some differences are encountered, the overall similarity in results points to the interconnectedness of the world during the period under study.
