Between 1990 and 1993, the Ligabue Study and Research Centre of Venice, in collaboration with the Centro de Estudios Isla de Pascua of the University of Chile, the Museo Isla de Pascua Sebastiano Englert and the Italian Precolumbian Archaeological Study and Research Centre, three successive missions to Rapa Nui were made with the aim of increasing knowledge of the inhabited and ceremonial settlements on the island. The purpose of this was to make a more comprehensive analysis including the Marquesas Islands, Fiji, Samoa and Tonga, the most probable route of the Polynesian migration.
