The World Dhammakaya Center Since 1984, the number of people joining the ceremonies of the temple exceeded its capacity and prompted the decision to expand the site and the building of the World Dhammakaya Centre, an area of two thousand rai (3.2 km2).

The design is based on the architectural style of different ancient stupas, among which are the stupas of Sanchi, Borobodur, Anuradhapura, Shwedagon and the stupas of the Pagan Kingdom. The Cetiya has the shape of a hemispherical dome, thirty-two meters high and hundred and eight meters in diameter. The hemispherical dome represents the Buddha, the surrounding inner terraces the Dhamma, and the granite outer terraces the Saṅgha. The exterior holds 300,000 Buddha statues, placed on the dome and the terraces. Each of the images has the name of the donor engraved in it, which is an old tradition. Inside the Cetiya are digitally preserved Buddhist texts, another 700,000 Buddha statues and a large central Buddha of made from sterling silver. The central Buddha image symbolizes the possibility of liberation through meditation.
