Prasat Khao Noi

Prasat Khao Noi is a Khmer ruin situated on a forested hill in Khlong Nam Sai, featuring a central brick tower that reveals ancient construction techniques. The structure stands distinct from its surroundings due to its height and compact form.

This sanctuary originates from the 7th century and contains one of the oldest Khmer inscriptions ever discovered within present-day Thailand's borders. The structure demonstrates the early spread of Khmer culture beyond its traditional settlement areas.

Local visitors leave flower garlands and offerings at the base of the tower, showing how this ancient site continues to hold spiritual meaning for the community. The blending of Khmer architecture with ongoing prayer practices creates a place where past and present coexist.

Access is through a staircase behind the nearby Wat Khao Noi temple with parking available along a path circling the hill. The climb is manageable for most visitors, though the ground can become slippery after rain.

The brick tower takes on a distinctive pinkish hue when sunlight strikes its surface, which inspired the site's local name. This coloring emerges from the specific composition and age of the materials used in construction.
