Ancient Underwater Wall of Nhon Hai in Quy Nhơn Đông, Vietnam
At the coast of Nhon Hai in Quy Nhon, a mysterious wall lies partly submerged beneath the sea.

In the coastal region of Nhon Hai in Quy Nhon, Vietnam, an intriguing underwater wall has captured the attention of both locals and researchers alike. This submerged structure stretches from the rocky coastline toward Hon Kho Island, becoming visible only during exceptionally low tides. Local fishermen have been familiar with the wall for generations, yet its exact age and purpose remain shrouded in mystery.
The wall's surface is notably flat and stretches over 10 meters wide in certain areas. Rather than being constructed from individually laid stones or bricks, local divers have noted that it is built from a dense, solid material reminiscent of mortar. Speculation has arisen regarding the wall's potential defensive or coastal-protection function, and some even draw parallels to the ancient Champa landscape in the surrounding region.
However, despite the local lore and visible characteristics, no archaeological evidence has definitively established the wall's origin or chronology. The phenomenon of certain sections of the submerged structure appearing above the water for a few days, around the lowest tides of the lunar month, adds an element of intrigue to the already enigmatic feature.
Its location between the mainland and Hon Kho Island, coupled with the changing visibility due to tidal fluctuations, makes the wall one of the more perplexing coastal landmarks in the Quy Nhon area.
