Ban Kruat or ‘The Stone Village’ was probably once the stone quarry used for the construction of the main monuments in the area such as Prasat Phanom Rung and Prasat Muang Tam. Comprising an area of about 480 hectares, the ancient quarry is situated on a raised platform which runs alongside the Huay Mekha Waterway, Khao Kloy and Khao Krajiao mountains. Holes drilled in a neat row and hollowed out squares and rectangles, form definite traces of the ancient quarry with some of the blocks still lying around in disarray.
