The Noushabad Underground City is an outstanding illustration of prehistoric engineering and clever planning. This amazing underground building, called Ouyi, is located close to Kashan, Iran, and it was built during the Sassanian era some 1500 years ago.

It displays an intricate system of chambers, tunnels, and strategically placed defensive elements that have been painstakingly built to fend against assaults. Visitors are engrossed in a historical story where villages previously thrived beneath the soil as they make their way through this secret maze.

The Historical Significance of Noushabad


Built for a variety of uses, the Noushabad underground city was constructed under the Sassanid Empire (also known as the Neo-Persian Empire), which lasted from 224 to 651. One of the Sassanid kings who traveled through this region gave the city the name Noushabad, which means “city of cold tasty water.” Its creation was partly motivated by the need to provide a means of escape from the intense heat of the Iranian desert region. However, the main driver for building the underground city was the history of raids and instability in the area. Invaders posed a continual threat to the inhabitants of ancient Persia, and the Noushabad underground city served as a safe refuge during conflicts and invasions.

Throughout the Seljuk, Safavid, and Qajar dynasties, the city kept growing. Numerous lives were spared from the unfathomable cruelty of the Mongol invaders in the 13th century and from the Arab invaders centuries earlier.

Architectural Marvel of the Sassanian Era

This historic subterranean city is a marvel of architectural design, its distinctive and complex layout offering advantages for both defense and utility.

People are able to live and work underground for lengthy periods of time without having to leave the city because of a network of tiny passageways, stairwells, and chambers that are arranged across three levels.

There were many entrances to enter the city, which ranged in depth from 4 to 18 meters. A few of these apertures were found in people’s homes, while others were found in public areas like the main fort outside the town.

The chambers’ arched ceilings and supporting pillars provide an amazing sight. They are sculpted out of soft limestone rock. In order to illuminate the gloomy, maze-like passageways and rooms, it also features fat-burning lamps set into carved crevices in the walls.

The city’s ventilation system is among its most remarkable characteristics. No matter how deep you go, fresh air is always available thanks to the clever architecture, which consists of a maze of rising and descending passageways and a network of air ducts that permit unrestricted airflow throughout the building.

The water supply system of the Noushabad Underground City is another remarkable feature. The town’s numerous subterranean wells and channels offer its citizens a dependable supply of water.

Strategic Defense and Urban Planning

Ouyi is special because of its defense features. Intruders find it challenging to negotiate the intricate web of routes connected by tiny hatches that can only accommodate one standing person at a time and the narrow paths that are only accessible by crawling. The intricate layout of the city further complicates access.

It provides its inhabitants total control over possible trespassers, enabling them to defend themselves from assailants. Additionally, because the U-shaped tunnels connected the various levels, the invading soldiers would have to strike towards the end of each tunnel, which would give the defensive soldiers an edge in height and time to dominate their enemies.

The rooms had deep holes in the center that were filled with revolving stones that would topple over if someone trod on them. Residents of old Noushabad and other adjacent villages would hide out in the Ouyi subterranean network when enemy forces raided the region above the city. To confuse the adversary, they would enter the building and go in a single-file line, with the first person lighting the wall-mounted torches and the last person shutting off the next torch.
