Beside the main road in Namadgut village, this crumbling ruin commands a view of the Pyanj from two riverside knolls. The oldest sections date to the 3rd-century BC (Kushan-era), but the site has been reused by many other cultures since. Indeed, part of the mound was used as a Tajik military watch post until very recently and an armed soldier may appear from behind the ruins if you wander off-piste.
There's a quaint mobile shop on-site.
