In 2001 the Taliban swept through Afghanistan's Bamiyan Valley.

As they captured the territory, Bamiyan's colossal stone Buddha statues - which stood for over 1500 years - were destroyed.

It took the Taliban four full days to destroy the statues using a mixture of cannons and explosives.

The world watched powerless as one of its true wonders was lost.

Rebuilding Bamiyan talks to one man who was forced at gun point to participate in the destruction, to some of those now participating in the painstakingly slow and dangerous attempt to restore the site and asks just why the Buddha's are so important to Bamiyan.
