They built big temples for their gods. One temple was for a god named Enki. 
People found many things in the dirt. They found a small boat made of clay. They also found a blue piece of glass. 
Some people lived in a large palace. The city was near the water.
Eridu is a very special place to study.
Eridu was a very old city in Iraq. 

People built big temples for their gods. One god was named Enki. He was the god of the waters. His temple was called E-Abzu. It means "House of the Aquifer." An aquifer is a place under the ground that holds water. 
Archaeologists study the city to learn about the past. They found many things in the dirt. They found a small boat made of clay. They also found a piece of blue glass. This glass is very old. It might be one of the oldest pieces of glass in the world. 
Later, the city began to change. The soil became too salty for farming. This happened because of how people watered the land. People left the city around 600 BC. Now, we study the ruins to see how they lived.
Eridu was a very important ancient city in southern Mesopotamia. 

Religion was a huge part of life in Eridu. The people believed the god Enki founded the city. Enki was the god of water and lived in a place called the Abzu. Because of this, his temple was named E-Abzu, which means "House of the Aquifer." An aquifer is a place underground that holds water. 
Archaeologists have spent a long time digging in the dirt to find Eridu. 

Many amazing objects were found during these digs. 

Eventually, the city could no longer support all its people. The soil became too salty because of how people watered the crops. This made it hard to grow food in the area. Because of this, the city was eventually abandoned around 600 BC. Today, researchers from Italy, France, and Iraq still study the site. They use new tools to make maps of the old streets. By studying Eridu, we learn how the very first cities in the world began to work.
Eridu was a foundational Sumerian city located in Lower Mesopotamia. 
The city's location was defined by its unique geography. Eridu sat on a natural hill within a large basin. This basin is known as the As Sulaybiyat Depression. During the rainy season, which lasts from November to April, the basin becomes a seasonal lake called a sebkha. This lake is filled by the discharge of the Wadi Khanega. A sandstone ridge called the Hazem separates the basin from the Euphrates River. In the 3rd Millennium BC, a canal named Id-edin-Eriduga connected the city directly to the Euphrates. This canal allowed for water transport and irrigation, though the river eventually shifted its course.
Religion was the central mechanism of life in Eridu. The city was believed to have been founded by the god Enki. Enki, who was later known as Ea, was the god of water. He was said to live in the Abzu, which is an aquifer where all life originates. Because of this connection to water, the main temple was named E-Abzu, or the "House of the Aquifer." 
Archaeological evidence shows that Eridu developed through several distinct stages. The city began during the Ubaid period on a virgin sand dune. During this time, the settlement covered about 12 hectares, or roughly 30 acres. As the city moved into the Uruk period, residents built more complex, non-secular buildings. In the Early Dynastic period, the city saw a massive increase in occupation. This era included the construction of a monumental palace. The site is organized into eight distinct mounds. Mound 1 contains the sacred area and the Enki temple. Mound 2 contains remnants of a city wall and an Early Dynastic palace. Other mounds, such as Mounds 3 through 7, hold various types of pottery from different eras.
History at Eridu is marked by many important people and discoveries. In 1855, John George Taylor first excavated the site and found inscribed bricks. Later, H. R. Hall discovered a piece of manufactured blue glass. This glass was made using cobalt and dates to the 21st century BC or earlier. It may be one of the earliest glass objects in the world. 

The decline of Eridu provides important lessons about environmental management. Archaeologist A. Leo Oppenheim suggested that the southern region eventually faced stagnation. This was likely caused by increasing salinity in the soil. Salinity occurs when salt builds up in the ground, often due to continuous irrigation. This salt made it difficult to grow enough food to support the population. As a result, the political power shifted to northern cities. Eridu was eventually abandoned around 600 BC. 
Today, Eridu remains a vital site for understanding human history. Since 2019, a joint effort by Italian, French, and Iraqi teams has resumed excavations. These researchers include experts from the University of Rome La Sapienza and the University of Strasbourg. They are using modern tools like photogrammetric mapping to create detailed maps of the site. They are currently focusing on the Ubaid period cemetery and residential areas. By studying these ancient layers, scientists learn how the first complex societies organized their governments and religions. Eridu connects our modern world to the very beginnings of urban life.
