Khon is a Thai classical dance drama often incorporating characters from the Ramakien, Thailand's own interpretation of the Indian classic Ramayana. The religious paraphernalia market within the grounds of Wat Ratchanatda sells Buddha images and Buddhist charms in all shapes and sizes as well as a variety of Indian Hindu deities and Chinese religious items. Wat Ratchanaddaram was built on the orders of King Nangklao (Rama III) for Mom Chao Ying Sommanus Wattanavadi in 1846. The temple is best known for the Loha Prasada (Loha Prasat), a multi-tiered structure 36 m high and having 37 metal spires. It is only the third Loha Prasada (Brazen Palace or Iron Monastery) to be built and is modelled after the earlier ones in India and Anuradhapura, Sri Lanka.
