What facility houses one or more cremation chambers?

A facility that houses one or more cremation chambers is known as a crematory. This is specifically designed for the process of cremation, where the deceased is placed in a cremation chamber and subjected to high temperatures that reduce the body to ash.

Crematories often have specialized equipment and facilities dedicated to this purpose, distinguishing them from other types of facilities involved in funeral services. While a funeral home may offer cremation as part of its service, it is primarily oriented towards broader funeral services and may not have the specific infrastructure dedicated solely to cremation. Similarly, a mausoleum is a structure designed for above-ground burial or entombment, and a mortuary often refers to a place where deceased bodies are prepared for burial, but it does not specifically constitute a crematory. Thus, the correct answer aligns with the definition and purpose of a crematory.
