The Buddhas of Bamiyan were two possibly 6th-century monumental Buddhist statues in the Bamiyan Valley of Afghanistan. Located 130 kilometres (81 mi) to the northwest of Kabul, at an elevation of 2,500 metres (8,200 ft), carbon dating of the structural components of the Buddhas has determined that the smaller 38 m (125 ft) "Eastern Buddha" was built around 570 CE, and the larger 55 m (180 ft) "Western Buddha" was built around 618 CE, which would date both to the time when the Hephthalites ruled the region. As a UNESCO World Heritage Site of historical Afghan Buddhism, it was a holy site for Buddhists on the Silk Road. However, in March 2001, both statues were destroyed by the Taliban following an order from their leader Mullah Muhammad Omar; the Taliban government of the Islamic Emirate had condemned the Bamiyan Buddhas as idols, invoking the Muslim concept of shirk. International and local opinion strongly condemned the destruction of the Buddhas.
