The exhibition of sandstone Buddha images within this museum features masterfully crafted sculptures that represent the historical transition between Dvaravati and Lopburi (Ancient Khmer) art styles, discovered across Chainat's key archaeological sites. Carved from natural grey and white sandstone, these statues demonstrate the exquisite skill of ancient artisans, particularly the Naga Prok (Serpent-shielded) images with their remarkably preserved facial features and intricate adornments. This display not only showcases powerful Buddhist artistry but also serves as definitive evidence of the flourishing Buddhist faith in the upper Chao Phraya basin that has remained deeply rooted for over a millennium.
