The ordination hall is a Buddhist building specifically consecrated and designated for the performance of the Buddhist ordination ritual (upasampada) and other ritual ceremonies, such as the recitation of the Patimokkha. The ordination hall is located within a boundary (sīmā) that defines "the space within which all members of a single local community have to assemble as a complete Sangha (samagga sangha) at a place appointed for ecclesiastical acts (kamma)." The constitution of the sīmā is regulated and defined by the Vinaya and its commentaries and sub-commentaries.
