A spirit house is a small structure found in many Southeast Asian cultures, particularly in Thailand. It is designed to provide a home for spirits, often believed to be the spirits of ancestors or local deities. These houses are typically placed in gardens, yards, or near homes, and they come in various styles and sizes. People often decorate spirit houses with offerings such as food, flowers, and incense to honor the spirits and invite their protection. The practice reflects a deep respect for the spiritual world and the belief that maintaining a good relationship with these spirits can bring good fortune and harmony to the household.
