The Bolaghi Gorge, a significant part of the plain of Pasargadae, the Achaemenid dynasty's first capital, is on the brink of submersion when the construction of a new dam is completed south of Iran.

The 18-km-long gorge is just 4 km away from the historical city, just inscribed on UNESCO’s prestigious World Heritage List in June. Archaeologists believe the gorge was part of the renowned Achaemenid Imperial Route, driven by mounted couriers to deliver royal messages from Pasargadae to Persepolis and Susa. 

 

The gorge also houses some residential caves, dating from the prehistoric to the Islamic period.

 

The dam construction began in 1992 by 'Sakou Company' which belongs to the Islamic Republic's Revolutionary Guards. Iran Cultural Heritage Organisation was not informed about the dam construction.

“The construction project of the Sivand Dam threatens to flood part of the historical site of Pasargadae, washing away many ancient and invaluable artifacts, mostly undiscovered,” warned Dr Masoud Azarnoush, head of the archaeological research center at Iran’s Cultural Heritage Organization (ICHO).

The dam would be operational in 2 or 3 years, inundating a stretch of over 8 km of the gorge, noted Babak Kial, head of the Pasargadae site. He called for accelerated efforts to salvage the would-be-submerged areas.

Other experts believe the submersion looms large not only for the gorge but also all structures and monuments in the site including the mausoleum of Cyrus the Great. 

 

However, it seems this is a 'negative-rumor' propagated by the Islamic Republic to divert attentions from main danger to Pasargadae, which is the effects of humidity on the edifice, generated from the artificial lake behind the dam. The extend of damage as the result of humidity is currently unknown.

 

Pasargadae covered an area almost 1.5 miles in length and included palaces, a temple and the tomb of the king of kings. The city was built on the site where King Cyrus defeated his grandfather, and the last king of Median dynasty, Astyages, in 550 BCE.

The heart of Pasargadae is the citadel, which is known as Tall-i-Takht or 'throne hill'. It overlooks a garden in the south, and the palace complex itself. This consists of two smaller units: the residential palace and the many columned audience hall. The audience hall or Apadana can be approached from the south-east; the visitor first has to pass a gate and then has to cross a bridge over the river Pulvâr.

The mausoleum of Cyrus the Great is situated a little to the southwest. It was venerated by later rulers, the Macedonian king Alexander, who ordered restorations in January 324 BCE. The tomb of Cyrus' successor Cambyses was never finished.

Even though Darius the Great built a new capital, Persepolis, 43 kilometers downstream along the river Pulvar, Pasargadae remained an important place, probably as the religious capital of the Achaemenid Empire where the inauguration of the kings took place.
