Prang Khaek is a compact group of three brick towers on Wichayen Road, between Wichayen House and Phra Prang Sam Yot. It is generally regarded as the oldest monument in Lopburi and one of the earliest Khmer-style buildings in central Thailand, dating from the period when the town was a Khmer outpost. It began as a Hindu shrine, which is reflected in its name.
Unlike Phra Prang Sam Yot, the three towers are not linked by passages. They were repaired in King Narai’s reign in the 17th century and have been restored by the Fine Arts Department in modern times. The site takes only a few minutes to see and is easy to fit into a walk around the old town.
