Sacristy

[citation needed] Sacristies usually contain a special wash basin, called a piscina, the drain of which is properly called a "sacrarium" in which the drain flows directly into the ground to prevent sacred items such as used baptismal water from being washed into the sewers or septic tanks.

The cruets, chalice, ciborium, paten, altar linens and sometimes the Holy Oils are kept inside the sacristy.

[5] In the Moravian Church, in addition to storing vestments and other vessels, the preparation room is where the Lovefeast is made ready for distribution to the congregation.

[2] In Eastern Christianity, the functions of the sacristy are fulfilled by the Diaconicon and the Prothesis, two rooms or areas adjacent to the Holy Table (altar).

[6] Work is planned to rebuild the demolished processional sacristy as an entry route for tourists and visitors to Westminster Abbey.
