Phra Prang Sam Yot is a 13th-century Khmer-style Hindu temple located in the heart of Lopburi, Thailand. It is defined by three distinct laterite and sandstone prangs (towers) connected by corridors, representing the Hindu trinity of Brahma, Vishnu, and Shiva. The site is famous for its large resident population of long-tailed macaques that occupy the ruins. It was originally constructed as a Hindu sanctuary before being converted into a Buddhist shrine during the Ayutthaya period. The architecture features delicate stucco carvings on the exterior walls, though much of the original detail has eroded over centuries. The temple grounds are open to the public, though the proximity of aggressive wildlife necessitates caution for all visitors. It serves as a focal point for the annual Monkey Banquet Festival held in the surrounding area.
