Phra Prang Sam Yot is Lop Buri’s best known landmark and provincial symbol. It is located on a mound on the west side of the railway near San Phra Kan. The compound comprises three prangs linked to one another by a corridor. It reflects the Bayon style of Khmer art during the 12th -13th century. It was made of laterite and decorated with beautiful stucco relief.

This is another former Brahman shrine located next to Phra Prang Samyot. The compound was built at two different times, and so has both an old and a new section. The former dates back to the Khmer period, as evidenced by a laterite mound uncovered hundreds of years later. The new section, constructed in 1951, contains a famous object of worship: a four-armed Vishnu figure affixed with a Buddha’s head.

This is a large royal temple in the center of Lopburi town. The main prang (spire) was built by the Khmer in the Bayon style around the late 12th century. The U-Thong style Buddha images on the prang and the large vihara were later added by King Narai the Great in the 17th century.
