Caves of Nanumanga

The Caves of Nanumanga, discovered in 1986 off the northern shore of Nanumanga, Tuvalu, are significant underwater structures that have sparked interest due to a local legend of a 'large house under the sea.' These caves, sometimes referred to as the Fire Caves of Nanumanga, are currently submerged, highlighting significant historical changes in sea levels. The presence of the caves suggests habitation or use during periods when sea levels were lower, potentially spanning periods from the Upper Paleolithic to Neolithic. This site contributes valuable insights into environmental changes and human adaptation over millennia, particularly in the context of Polynesian history and culture.
