Located on Vichayen Road, approximately 200 meters from the railway station, Phra Prang Sam Yot is Lop Buris best known landmark and provincial symbol. A former Hindu Shrine built in the 13th century in the classic Bayon style of Khmer architecture, the compound comprises three prangs (towers) linked by a corridor. The three laterite and sandstone spires decorated with classic stucco are believed to have originally represented the Hindu Trimurti; Brahman (the creator), Vishnu (the preserver) and Siva (the destroyer). During the reign of King Narai, the shrine was converted into a Buddhist temple when a brick viharn located to the east which houses a grand U-Thong-Ayutthaya style Buddha image was probably built. Buddha images were later added to the two prangs. 

The temple is open at 8.00 a.m. until 6.00 p.m.

The admission fee is 50 baht each. A package ticket is also visiting at 150 baht each, covering admission to Vichayen House, Wat Phra Si Maha That and Kraison Siharat Hall.
