The Inverted Stupa Shadow is an "Unseen Thailand" phenomenon found in several Lampang temples, such as Wat Phra That Chom Ping and Wat Phra That Lampang Luang. This phenomenon occurs when the image of the stupa outside passes through a small hole or gap in the building's wall or window (Viharn or Ubosot) and is projected onto a screen or surface inside in an inverted (upside-down) position. Scientifically, this is the "Camera Obscura" effect, where light travels in a straight line through a pinhole to create an inverted image. However, in Buddhist belief, locals regard it as a divine miracle reflecting the sacredness of the Buddha's relics enshrined within the stupa.
