Sunken ancient city

 　　Whenever the city lights are on, neon lights reflect the bustling streets, and supermarkets are crowded with people, you can't imagine what it would be like if the city was buried in the deep sea one day. However, archaeologists have discovered cities that disappeared in the Middle Ages or ancient times, buried deep in the sea through bewildering seabed investigations. On the deep blue or deep black seabed, when people poke through the thick water plants and see the ruins of ancient cities, how charming and magical it must be!

　　Due to the increasing development of undersea archaeology, many ancient cities that have sunk to the bottom of the sea due to changes in the crust have been revived one by one. Italian underwater archaeologist Zalde Chalo discovered a historical city that people have never found: the ancient port city of Pilki on Andros Island. Once, at a depth of 20 meters underwater on a seashore, Zardchalo pulled away the long water plants and found that the water plants were actually attached to some marble columns. Based on his findings, he continued to track and search, and found another Fragments of many ruins of ancient houses and statues, and even the outlines of squares, streets and harbour piers are faintly discernible, forming a magnificent ancient port city. Later, according to historians, it was confirmed that this is the historical city that people have been unable to identify. Then, the underwater archaeologist also discovered 30 underwater ancient cities, one of which is the ruins of a city sunk on the seabed not far from Venice and Sinapoli. It extends parallel to the coastline for 5 kilometers and exists in before the founding of the Roman Empire.

　　Undersea archaeology is a very meticulous and complex work, and in order to obtain data, great labor is required. The ancient Greek philosopher Plato once described the prosperity of the continent now located in the Atlantic Ocean. Marine scientists have worked hard to find the whereabouts of the missing continent hundreds of miles away from the west coast of Portugal. 460 photos were taken, one of which shows long platforms one metre wide, the location and regular shape of these platforms, as evidenced by the fact that it was hand-crafted. So a hypothesis was put forward, that the ruins are likely to be the remains of the Great Western Continent.

　　In the 17th century, Port Royal on Jamaica Island in the Latin American Caribbean Sea was a prosperous city. Because of its geographical location, it happened to be on the edge of the Puerto Rico Sea in the Atlantic Ocean. The deepest trench here is more than 8,300 meters, extending an area of ​​186,000 square meters. km, the submarine volcanoes erupt frequently in this area. As a result, the city sank to the bottom of the sea under three consecutive strong earthquakes. In recent years, some undersea archaeologists have come to the Caribbean Sea to survey the seabed of this city, which was once a gathering place for European pirates and colonialists. American scientists took the observation submarine to dive. They used advanced detection instruments such as side sonar and electromagnetic current needle to obtain detailed information about the ruins of the ancient city and the vicinity of the seabed, and drew a map of the ancient city and hydrological and geomorphological maps of the sea area. The divers are still in the ancient city ruins. Many household furniture and ancient cultural relics were salvaged nearby. What is even more interesting is that among these ancient cultural relics, there is a bronze self-ringing bell. The pendulum of the needle stopped swinging due to the broken string during the earthquake. After X-ray examination, it was proved that the time pointed by the self-ringing clock was exactly the exact time of the strong earthquake. time. Ancient bells provide conclusive evidence for seismologists to study the specific time and situation of local earthquakes, and also provide valuable technical data for marine geoscientists' research work.

　　The discovery of underwater ancient cities by underwater archaeologists has provided us with a lot of precious historical research materials. There is a city of Bondioscura that was submerged by the sea at the end of the 4th century BC. This is a Greek city built by immigrants from Miletus in the 6th century BC. At that time it was one of the important international business centers. The market there is prosperous and prosperous, and merchants from Greece, Rome and Asia Minor compete to come here to trade, and the traffic is very busy and prosperous. However, nature is like a magical magician who buried this famous city under the sea with the intense crustal movement of the Caucasus Mountains. Today, it only leaves a pile of rubble and broken walls, but archaeologists have provided us with extremely important evidence and physical data. People seem to see groups of people gathered in the square, looking forward to various commodities. Many merchants are trading, and the slaves on the dock are carrying heavy goods and walking with difficulty...

　　For more than a thousand years, the myths of ancient Greece have been circulating such legends. On the Mediterranean side of the northern part of ancient Egypt, there used to be an extremely powerful and civilized city - "Pharaoh City". There are majestic "Hercules" temples in the city, many statues with artistic value, and various simple and elegant buildings... The people here live a very prosperous and comfortable life. And the highly developed civilization of the pharaoh city is also thousands of years earlier than the civilization of the rest of the world. However, one night 1,400 years ago, the pharaoh city disappeared. It lay on the seabed 40 meters deep. The temples, statues and houses existed intact. Myths and legends finally became reality. Archaeologists believe this is the greatest discovery in the history of marine archaeology. It was caused by a sudden earthquake 1,400 years ago that caused the ground to sink suddenly, and the sea swelled and sank to the bottom of the sea.

　　On the red earth plateau in Yunnan, my country, there is a beautiful lake with a water depth of 155 meters, which is the second largest deep-water lake in my country. This is Fuxian Lake. Legend has it that in ancient times a city sank into the lake and disappeared without a trace. For a long time, no one took this legend seriously. It was not until May 1992 that a diving enthusiast discovered the ruins of the ancient city underwater. interest. On March 1, 2001, Yu Xixian, an archaeologist from Peking University, conducted on-site research, and took a lot of TV and photo data, and salvaged artificially carved stones from the scene. After comprehensive analysis of the data, it was confirmed that Fuxian Lake was underwater. There are ancient civilization sites. Then, the Chinese Underwater Archaeology Team gathered elite soldiers, experts in archaeology, geology, history, earthquake, and ancient architecture, and actively participated in it. With the assistance of underwater robots and submarines, they finally verified and discovered the underwater buildings of Fuxian Lake. The site is 1,200 meters long from east to west and 2,000 meters wide from north to south, which is rare in my country. The ancient architectural site was built no later than the mid-Eastern Han Dynasty and has a history of at least 1,700 years. This is the first underwater ancient architectural site discovered in my country. Experts speculate that this is an underwater city that sank to the bottom of the lake due to a landslide, or that it sank due to an earthquake.

　　The sea is like a weather-beaten old man, who is constantly telling people the history of the prosperous ancient cities in the past.
