Chofa (Thai: ช่อฟ้า, pronounced [t͡ɕʰɔ̂ːfáː]; lit. sky tassel) is a Lao and Thai architectural decorative ornament that adorns the top at the end of wat and palace roofs in most Southeast Asian countries, such as Thailand, Cambodia, Laos, and Myanmar. It resembles a tall thin bird and looks hornlike. The chofa is generally believed to represent the mythical creature Garuda, half bird and half man, who is the vehicle of the Hindu god Vishnu.
The representation of cho fah is unclear and believed to represent garuda, however, the present research indicates that the original chofah upon which most subsequent chofah have been based is the gajashimha of Suryavarman II, the Khmer king who built Angkor Wat.
Temple finials representing gajashimha was presumably appeared in Cambodia during or shortly after his reign (1113 AD to 1150 AD). These finials (chofah) symbolized the unification of the northern and southern Khmer kingdoms and the reign of King Suryavarman II. This symbolism spread extensively throughout the region including part of today Laos, Lanna, and Isan which were once the Khmer empire.
