Prasat Andet is located northwest of Provincial Town of Kampong Thom, in Prasat Village, Sankor Commune, Kampong Svay District. The temple was built in second half of 7th century (627-707) during the reign of king Jayavarman I to dedicate to God Hirihara, in Kampong Preah style and made of brick with masonry, laterite and sandstone. Prasat Andet had isolated plan, built on a 5.30-meter height artificial hill, and was form in rectangular shape with 7.50-meter length, 5.50-meter width and 1-meter thick (interior to exterior). It was facing to the East. The lintel of Prasat Andet was carved in the garlands and carefully done in the traditional khmer style.
The coronet (2.22 lengths) was ornamented around by the rings decorated, and at between of the rings we decorated with garland and bulb flowers surrounded, which are joining each other by the end of the decorations. In original former time, this temple contained Harihara Statue standing on a decorative royal throne, and the statue was brought to be kept at Phnom Penh National Museum. The Harihara statue is a body side’s Siva and another body side’s Vinu. The framed door had 1 m width, 2m height and 0.20m thick. On the northern framed door, we saw the marks of a cloven hoof of tiger cat that used to go to the upper box of the door, which remained the marks until now.
