Tangeh_Bolaghi
Tangeh Bolāghi, also transliterated as Tange-ye Bolāghi[1] (Persian: تنگه بلاغی), or Bolāghi Gorge, is an archaeologically significant valley consisting of 130 ancient settlements, dating back to the period between 5000 BCE and the Sassanian dynastic era (224-651 CE). It is situated in Iran’s southern province of Fars, some 7 kilometres from Pasargadae, Iran. This is the valley of the Polvar River, a tributary to Kor River.
Archaeological research since 2005 have discovered a section of the Royal Road (Rāh-e Shāhi — راه شاهی) connecting Pasargadae to Persepolis, Susa and other regions of the Persian Empire up to Sardis. Excavations have provided archaeologists with a unique insight into the lives of the people living in the Achaemenid dynastic era.
