Archaeologists have discovered an underground settlement in Iran, revealing more secrets of the past. (See photos)

In the central Iranian province of Yazd, archaeologists have uncovered an underground settlement beneath five historical houses in the ancient city of Abarkuh. Experts believe that these structures may provide significant insights into the cultural heritage of the region, writes Arkeonews.

The city of Abarkuh, located approximately 140 kilometers southwest of Yazd, is strategically situated in a historic triangle formed by Shiraz, Yazd, and Isfahan. This location has ensured its importance throughout history.

Recent discoveries in the area include a network of underground chambers, tunnels, and a stone-paved aqueduct. Hossein Hatami, the governor of Abarkuh, explained in an interview that these underground spaces were likely designed for managing water resources, security, and daily life.

Old aerial photographs show that residents built houses on rocky foundations, transforming the spaces between them into gardens and pathways.

These tunnels showcase the advanced construction technologies of past civilizations. Hatami described the presence of carved steps along these routes, intended for accessing water conveyance systems, such as the qanats—traditional underground water channels.

The aqueduct, believed to date back to the Qajar era (the Turkic-Persian dynasty of Iranian kings from 1787-1925), is a testament to the engineering prowess of that time. Additionally, cooling corridors allowed residents to escape the intense summer heat, while large chambers likely served as relaxation areas or seasonal residences.

The underground complex may also have functioned as a refuge during conflicts. Scholars estimate that about 60 hectares of the historical part of Abarkuh are connected to these pathways, although modern construction and sewage systems hinder comprehensive exploration.

With over 400 historical sites in the region, 147 of which are registered as national heritage sites, Abarkuh remains a cultural hub, home to attractions such as its famous 4,000-year-old cypress tree.

The discovery of the underground city not only enriches our understanding of ancient Abarkuh but also showcases the ingenuity of its former inhabitants. These findings underscore the importance of preserving the region's unique historical landscape.
