Deep sea discoveries that show huge ancient cities exist on the ocean floor
Underwater discoveries are, by their very nature, baffling to behold and whilst some of these cities are known to history others are mysterious and unexplained. Today marine archaeologists, historians, and divers explore these submerged cities almost as much as they explore ancient ruins on land, due to recent technology advancements in equipment such as, robots, submarines, and underwater cameras. Who knows what artefacts and relics they will bring up from the sea in the near future.
