The exact date Prang Khaek was constructed is unknown but it has been suggested that the temple was constructed in the 15th century (c.1050 AD)[1] or 16th century (c.1150 AD)[2] of the Buddhist calendar, given the architectural similarities to other Angkorian temples of the Suryavarman II era.
This makes Prang Khaek the oldest Angkorian temple in Lopburi and Central Thailand.
[5] It was believed to be originally built only of brick, but during King Narai's reign, the structure was reinforced with stucco.
Furthermore, two more structures were constructed in this period: a prayer hall (Vihara) at the front, and a water collection tank at the rear.
[6] Today it stands on the traffic island at the intersection of Sura Songkhram and Wichayen Roads.
