What is the name for chambers where urns are stored in burial practices?

The term for chambers where urns are stored in burial practices is "columbaria." These structures are specifically designed to hold multiple urns containing the ashes of the deceased. In ancient Rome, columbaria often resembled small niches or compartments that were intricately designed, and they could be found in both public and private burial sites.

Columbaria represent a significant aspect of Roman funerary customs, where cremation became a common practice, and the ashes were preserved in urns. The careful construction and design of these spaces highlight the importance of honoring the deceased and ensuring that their remains were treated with respect suitable for their memory.

The other options serve different functions within the context of Roman funerary practices. For instance, "laudatio" refers to a eulogy or funeral speech, while "lectus funebris" is a funeral bed used for displaying the body before burial. "Puticuli" are burial pits or tombs, typically used for more mass interments. These terms, while related to funerary customs, do not specifically denote storage chambers for urns.
