Qah-Qaha

The Qah-Qaha fortress, also known as Khakhka, rises above the village of Namadgut in the Wakhan Valley of Gorno-Badakhshan, perched on a cliff about 125 metres over the left bank of the Panj river at roughly 2,642 metres elevation. Archaeologists trace its origins to around the 3rd-2nd century BCE, during the era of the Kushan Empire, when it was built to guard the Silk Road caravan routes linking China and India through this narrow high-altitude corridor. The fortress is unusually large and complex for the region, measuring about 675 metres from west to east and 220 metres north to south, with an inner citadel enclosed by its own walls set within an outer defensive perimeter studded with some 56 round watchtowers, all raised from local stone and mud on a natural rocky outcrop. Local legend attributes the fortress's name to a giant ruler called Qahqaha, said to be the brother of the rulers of the nearby Yamchun and Khaakha strongholds.
