Tangeh Bolaghi

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.

Prior to Sivand Dam being completed in 2007, rescue archaeology was conducted in the area.

In May 2005, archaeologists unearthed a complete human skeleton at one of the excavation sites, thought to date back to the Sassanid era (224–651).

In April 2006 this find was overshadowed by the discovery of the 7000-years old skeleton of a young woman dating from the Tell-i Bakun Era (the fifth and fourth millennia BC) by a joint Iranian-German team of archaeologists in the same area.

[2][3] When the Sivand Dam came into full service in 2007, part of an ancient site including the Achaemenid Shah's Road between Cyrus's tomb and Pasargadae, 130 ancient settlements and a palace ascribed to Darius the Great may have been immersed in water from the rising Polvar River.
