Huge statues of giants called "YAK" stand in front of temples. They intend to frighten the spirits and protect the Buddha statues from the spirits.

The most famous "YAK" in Thailand are located in the Royal temple "WAT PHRA KAEW" (วัดพระแก้ว) in Bangkok. This temple contains the famous Emerald Buddha statue made of jade. It is said that the jade is coming from a mountain where "YAK" are supposed to have been living long ago.
