constructed by the third Angkorian-era king Indravarman, and was later laid with several additions from future kings, although all additions remained within the Khmer architectural style. The exact date of construction is unsure, although it has been dated back to the late 9th century, which the latter-additions dating as late as the 12th century. Like a lot of the Angkorian temples at the time, it's surrounded by a moat and heavy vegetation. Often referred to as one of the ruins in better condition, it is a must-visit for any travellers in the area. There are several brick towers surrounding the central pyramid structure. The area within the moat is about 650x850, and can be explored within an hour or two, preferrably in the morning as the light will be best for viewing and photography.
