The Phimeanakas temple is one of the earliest temples constructed in the area that would go on to serve future generations of kings as the Royal Palace up until the mid-15th century at least. Phimeanakas temple can be dated by its inscription, one providing a date of early 10th century, but some prefer to date it by art style which is attributed to the Khleang style in reference to the North and South Khleang buildings 500m to the east that are dated to the early 11th century for reasons we will get to.
