The Pagoda contains the world's largest pillar-less stone dome structure and is expected to attract hundreds of thousands of visitors from all over the world wanting to learn more about it and Vipassana meditation. Architecturally, this building is by far the largest single-span stone dome in the world, twice as big as the Basilica of St. Peter at the Vatican. At its centre is a circular meditation hall, 280 feet in diameter, which has a seating capacity of 8,000. At 325 feet height, it is almost as tall as a 30-story building. Approximately 2.5 million tons of stone was used in the construction.
