A pagoda is the general term in the English language for a tiered tower with multiple eaves common in Nepal, India, China, Japan, Korea, Vietnam, Burma and other parts of Asia. Some pagodas are used as Taoist houses of worship. Most pagodas were built to have a religious function, most commonly Buddhist, and were often located in or near temples. This term may refer to other religious structures in some countries. In Vietnam, pagoda is a more generic term referring to a place of worship, although pagoda is not an accurate word to describe a Buddhist temple. The modern pagoda is an evolution of the Ancient Nepal stupa, a tomb-like structure where sacred relics could be kept safe and venerated. The architectural structure of the stupa has spread across Asia, taking on many diverse forms as details specific to different regions are incorporated into the overall design.
