In the striking Bamiyan Valley of Afghanistan, on the side of a cliff, stood two prodigious Buddha statues that dated back to the 6th-century AD. Popularly known as Bamiyan Buddhas, they were constructed before the advent of Islam in central Afghanistan. The Taliban forces had destroyed them in 2001, under the orders of leader Mullah Mohammed Omar. But thanks to technology, the Buddhas came back to Bamiyan in 2015 in the form of  3D light projections.
