In traditional Persian architecture, a howz () is a centrally positioned symmetrical axis pool. If in a traditional house or private courtyard, it is used for bathing, aesthetics or both. If in a sahn of a mosque, it is used for performing ablutions. A howz is usually around deep. It may be used as a "theatre" for people to sit on all sides of the pool while others entertain.
