Totally artificial, this ‘great cave’ is where the Sixth Buddhist Synod was held in 1954–56 to coincide with the 2500th anniversary of the Buddha’s enlightenment. Measuring 456ft by 371ft, the cave, which can accommodate up to 10,000 people, took only 14 months to build. It helped that there were 63,000 labourers. Grand religious ceremonies are still held here.
