(3) The other structures of the Yonaguni monument include ruins of a palatial building, which could be a castle as well, five temples, a triumphal arch and a large stadium. All these structures are apparently connected with roads and water channels, which clearly indicates that human intelligence was deployed to create these megalithic structures.

Many scientists have put forward the theory that the city which existed about 10,000 years ago sank under the sea owing to a sudden seismic movement like a giant tsunami. They have drawn references of this theory with the Indian sunken city of Dwarka, where stone monuments are found submerged under the water.
