Bamiyan lies on the Silk Road, which runs through the Hindu Kush mountain region, in the Bamiyan Valley. The Silk Road has been historically a caravan route linking the markets of China with those of the Western world. It was the site of several Buddhist monasteries, and a thriving center for religion, philosophy, and art. Monks at the monasteries lived as hermits in small caves carved into the side of the Bamiyan cliffs. Most of these monks embellished their caves with religious statuary and elaborate, brightly colored frescoes. It was a Buddhist religious site from the 2nd century up to the time of the Islamic invasion in the later half of the 7th century. Until it was completely conquered by the Muslim Saffarids in the 9th century, Bamiyan shared the culture of Gandhara.
The two most prominent statues were the giant standing Buddhas Vairocana and Sakyamuni, identified by the different mudras performed. The Buddha popularly called "Solsol" measures 53 meters tall, and "Shahmama" 35 meters -- the niches in which the figures stand are 58 and 38 meters from bottom to top.[8][9] Before being blown up in 2001 they were the largest examples of standing Buddha carvings in the world (the 8th century Leshan Giant Buddha is taller,[10] but the statue is sitting). Since then the Spring Temple Buddha has been built in China, and at 128 m (420 ft) it is the tallest statue in the world. Plans for the construction of the Spring Temple Buddha were announced soon after the blowing up of the Bamiyan Buddhas and China condemned the systematic destruction of the Buddhist heritage of Afghanistan.
The smaller of the statues was built between 544 and 595, the larger was built between 591 and 644.[11] They are believed to have been built by the Kushans, with the guidance of local Buddhist monks, at the heyday of their empire. The larger figure was also said to portray Dīpankara Buddha. They were perhaps the most famous cultural landmarks of the region, and the site was listed by UNESCO as a World Heritage Site along with the surrounding cultural landscape and archaeological remains of the Bamiyan Valley. Their color faded through time.[12]
Chinese Buddhist pilgrim Xuanzang visited the site on 30 April 630 AD,[13][14] and described Bamiyan in the Da Tang Xiyu Ji as a flourishing Buddhist center "with more than ten monasteries and more than a thousand monks". He also noted that both Buddha figures were "decorated with gold and fine jewels" (Wriggins, 1995). Intriguingly, Xuanzang mentions a third, even larger, reclining statue of the Buddha.[3][14][15] A monumental seated Buddha, similar in style to those at Bamiyan, still exists in the Bingling Temple caves in China's Gansu province.
The destruction of the Bamiyan Buddhas became a symbol of oppression and a rallying point for the freedom of religious expression. Despite the fact that most Afghans are now Muslim, they too had embraced their past and many were appalled by the destruction.
