The Tak Ab Gorge is located 20 km. northeast of Behbahan, and is also known as ‘Darband-e-Pars’. In the natural terrain of this gorge, parts of the gravel walk or flagstones (for the royalty) from the Achaemenian era have been remained. On the top of Khaviz Mountain and at the highest point of gorge, there are two engravings of prose and poetry from the Qajar period. There had also been another epigraph consisting of seven lines in the ‘Kufic’ script which was unfortunately destroyed in explosion for the construction of the Maroon Dam.
