craftsmanship. In repairing and strengthening the royal carriage, efforts were made to reduce the weight of the royal carriage, while retaining the magnificence of traditional Thai art. This was achieved in the renovation in 1987. The Royal Great Victory Carriage has been built following the concept of Buddhist cosmology, in which Mount Sumeru is believed to be the epicenter of the universe and the abode of the god Indra, the head of heavenly beings. The royal carriage is modeled after the mythological Mount Sumeru, with the roofed throne as its symbol. The square-based structure upon which the royal urn is placed is open on all sides, with a sloping roof in three descending stages, elaborately carved and decorated.
