The Buddhists had arrived here in the second century and their kings ruled the valley for more than 500 years. Chinese explorers wrote stories of how there were 1,400 Buddhist monasteries along the banks of the River Swat, and the magical sound of temple bells would ring out across the valley. The temples are long gone, but almost anywhere you go in Swat, amid all the primroses and other wildflowers, you find their remains.
