The land on which the temple now stands was formerly designated by King Nangklao as a coffee plantation. However, after his death, his successor King Mongkut decided to build a temple on the land instead. According to King Mongkut the three principal temples in the old capital city of Ayutthaya were; Wat Mahathat, Wat Ratchaburana and Wat Rachapradit. Ever since the establishment of Bangkok as the capital city in 1782, only two temples with those names were built; Wat Mahathat and Wat Ratchaburana. The king was determined therefore to build a temple with the name Wat Rachapradit for the people of Bangkok. The king encountered a problem when he found the land too soft, being next to a canal. To solve this problem the king decide to host a public performance of Thai traditional dance on the site. The cost of admission being an empty garlic jar per audience. These garlic jars were then collected and used by the king's workmen as the foundation of the main ordination hall of the temple. Construction began in 1864 and was completed seven months later. The temple's full name as given by the king was Wat Ratchapradit Sathit Mahasimaram. As the temple's first abbot, the king appointed Sa Pussadeva, a monk from Wat Bowonniwet Vihara. A member of the Dhammayuttika sect, the abbot made Wat Rachapradit the sect's first temple. In 1893 King Chulalongkorn would make the abbot Supreme Patriarch.
Structures
The main structure is the Phra Viharn Luang, it is both a Vihāra and an ordination hall. Situated on a raise platform the Phra Viharn Luang is covered on the outside with grey marble tiles. The pediment depicts a golden royal crown on a blue glass background, the crown was the emblem of King Mongkut. The central door and two windows on either side are framed in gilded teak. Above them are traditional crown-shaped pediments, an allusion to the king's emblem. Inside are murals painted in the reign of King Chulalongkorn, depicting royal festivals of the twelve months. The main Buddha image is a replica of the Phra Phuttha Sihing, underneath it are interred the ashes of King Mongkut. On the wall opposite the Buddha image is a mural depicting King Mongkut watching the solar eclipse at Wakor village, Prachuap Khiri Khan Province on 18 August 1868. The Pasana Chedi or the 'Stone Chedi' is a large Sri-Lankan style stupa, which is situated behind the Phra Viharn Luang. The stupa is covered in grey marbles tiles and was built by King Mongkut. On either side of the Phra Viharn Luang are two almost identical white shrines, with a prang-style spire on the top, these are termed prasat and denote specially royal or sacred buildings. The eastern shrine is the Ho Trai or the library of sacred texts. The pediment features scenes of the Buddha's birth and his passing into Parinirvana. To the west is the Ho Phra Chom, decorated with the faces of Brahma on four sides. Inside the shrine is a life-sized statue of King Mongkut in gilded bronze. around these main buildings are smaller stupas containing relics of various monks including the temple's first abbot. Like the two shrines, these smaller stupas were built during the reign of King Vajiravudh, in the early 20th century.
