More than two thousand years before modern engineers bored tunnels beneath rivers and seas, ancient writers told of an astonishing passage hidden beneath the waters of the Euphrates. According to these accounts, a brick-lined tunnel ran beneath the river at Babylon, linking the city's two halves and allowing people to cross unseen below the current. If the story is true, the Euphrates Tunnel may have been the world's first underwater tunnel—a feat of engineering centuries ahead of its time. However, no trace of the structure has ever been found, leaving historians to wonder whether it was a genuine marvel of ancient engineering or another one of history's enduring legends.

According to ancient accounts, a tunnel once ran beneath the Euphrates River in the city of Babylon, connecting its eastern and western sections. The structure was reportedly lined with brick masonry and waterproofed with bitumen, a naturally occurring petroleum substance that was widely used in Mesopotamia for construction and waterproofing.
The project is most commonly attributed to the legendary Queen Semiramis, although some versions of the story credit another Babylonian queen. Ancient writers claimed that the tunnel allowed people to cross beneath the river without relying on boats or bridges, providing a secure and convenient route between the two halves of the city. If these descriptions are accurate, the Euphrates Tunnel would represent one of the most ambitious engineering achievements of the ancient world.
The primary descriptions of the tunnel come from classical authors such as Diodorus Siculus (1st century BCE) and Philostratus (3rd century AD). Writing centuries after the supposed construction of the tunnel, these authors described Babylon as a city filled with extraordinary monuments and engineering works.
Diodorus, in particular, recounted the existence of a passage beneath the Euphrates, describing how the river was temporarily diverted during construction so that workers could excavate and build the tunnel. Once completed, the river was allegedly returned to its original course, leaving the tunnel hidden beneath the water. The tunnel itself was described as 12 feet high and 15 feet wide. At either end of the tunnel were two massive bronze gates.
These accounts have fascinated historians for centuries, but they also raise important questions about their reliability.
Despite extensive archaeological excavations at Babylon, no physical remains of the Euphrates Tunnel have ever been discovered. Archaeologists have uncovered city walls, palaces, temples, and countless artifacts, but no trace of the tunnel itself has emerged.
This absence of evidence does not necessarily prove that the tunnel never existed. Over thousands of years, changes in the river's course, flooding, erosion, and human activity may have destroyed or buried any remains. Nevertheless, the lack of archaeological confirmation means that the tunnel's existence cannot be regarded as proven.
Another challenge is the nature of the written sources. The authors who described the tunnel lived long after the period in which it was supposedly built. Their accounts were based on earlier traditions rather than direct observation, making it difficult to separate historical fact from legend.
The figure most often associated with the tunnel, Semiramis, occupies a curious place between history and mythology. She was likely inspired by Shammuramat, a real Assyrian queen who lived in the 9th century BCE. Over time, however, stories about her grew increasingly extravagant.

Ancient legends credited Semiramis with founding cities, conquering vast territories, and constructing monumental works throughout the Near East. Many historians believe that numerous engineering projects attributed to her were later inventions or exaggerations designed to enhance her legendary status. As a result, the connection between Semiramis and the Euphrates Tunnel is often viewed with caution.
Although direct evidence is lacking, the idea of such a tunnel is not entirely implausible. The civilizations of Mesopotamia possessed impressive engineering capabilities. They constructed extensive canal networks, irrigation systems, embankments, and large-scale brick structures. Babylon itself was renowned for its sophisticated urban planning and hydraulic works.
Ancient builders were familiar with techniques for diverting rivers, controlling water flow, and constructing waterproof structures using bitumen. In theory, these skills could have made the construction of a river tunnel possible, though it would have been an extraordinarily challenging undertaking for the time.
Whether the tunnel described in the ancient sources accurately reflects a real structure, a smaller passage that was later embellished, or a purely legendary creation remains uncertain. In many ways, the tunnel's status resembles that of the Hanging Gardens of Babylon—another celebrated wonder known primarily through ancient descriptions rather than definitive archaeological evidence.
