The mysterious ruins of Malden Island, in the Pacific Ocean

The remote islands of the Pacific are often characterized by megalithic idols and elevated structures (the characteristic "Marae"), once used during sacred rites. Malden Island is no exception, also presenting, among the various sites of archaeological interest, huge streets paved in basaltic stone that nowadays disappear among the ocean waves: an apparently inexplicable discovery that has suggested to researchers the hypothesis of existence, in the past remote, of a lost continent.
