A sopo is a treasury structure in the architecture of the Toba Batak people from North Sumatra, Indonesia. Its form is similar to that of a Batak traditional house with the exception of being smaller in size and a construction ritual that is the opposite of a Batak house. Sopo is used as a repository for various items, e.g. rice, magical items, or trophies. Sopo can also be used as a meeting point for social activities.
