The second edition of “Elements of Thai Architecture” presents a rare and valuable collection of photographs of Thai architecture taken by Anuvit Charernsupkul approximately 40–50 years ago. This photographic archive, consisting of over 150 images, holds immense historical value. It captures significant architectural details such as the pediment of the directional prang at Wat Mahathat in Sukhothai, the gabled prang hall at Wat Mahathat in Lopburi, the stupa wall of Wat Cham Thewi (Wat Ku Kut) in Lamphun, the façade of the vihara at Wat Lai in Lopburi, the Naga stairway of Wat Phra That Chae Haeng in Nan, the exterior grounds of Wat Kasatraram in Ayutthaya, and the interior of Wat Yai Suwannaram in Phetchaburi, among many others. These images offer an unparalleled glimpse into the exquisite craftsmanship and architectural environments of various historical periods—preserved in their authentic condition before being altered or destroyed by both human intervention and natural decay.
