The site was designed to replicate the layout of the Angkor Wat temple in Cambodia.
The name 'Nakhon Luang' translates to 'Royal City' or 'Capital City'.
It served as a strategic stopover for royal processions traveling to the Buddha Footprint temple in Saraburi.
The structure underwent a significant preservation project by the Fine Arts Department in the 1990s.
Evidence suggests the site was built atop an older, pre-existing structure.
The castle houses a collection of various Buddha images placed in the galleries by local devotees over the decades.
Prasat Nakhon Luang is a 17th-century Khmer-style castle located in the Phra Nakhon Si Ayutthaya province of Thailand. It was originally built during the reign of King Prasat Thong as a royal residence and a resting place for kings traveling to and from the royal footprints at Saraburi. The structure features a large, elevated square platform constructed from brick and laterite. Its architecture reflects Khmer influence, notable in its tiered levels and corridors containing Buddha images. Despite its historical age, the site remains an active location for local religious worship. The castle was extensively restored to stabilize its structure and preserve its remaining decorative elements. It sits along the banks of the Pa Sak River, which historically served as a major transport route.
