The Bot or Ubosot is the main prayer room and one of the most important structures of the Buddhist Temple. This is the building where monks get ordained. It is also used for other important temple rituals. The bot is a rectangular shaped building with the main entrance facing East. Across from the main entrance sits a glided sitting Buddha image on a richly decorated pedestal. A bot is surrounded by eight boundary stones called sima or sema, that are placed outside the bot in a rectangular shape. A bot and a viharn will usually have similar characteristics, but a viharn does not have the sima stone markers.
