What is the name of an outer enclosure consisting of a body and a one or two piece lid?

The correct answer is the grave box. A grave box is an outer enclosure designed to contain a casket and is typically constructed as a solid unit that includes a body and one or two-piece lid. This design provides an additional layer of protection for the casket as it is placed in the ground, helping to maintain the integrity of the burial site over time.

The purpose of a grave box is not only functional, providing structural support and protection, but it also adds a level of aesthetic appeal to the burial. It serves to shield the casket from the elements and from potential disturbances that could occur in the cemetery environment.

In contrast, while a grave liner is also designed for encasing a casket, it typically refers to a less substantial outer container that might not have a solid construction as a grave box. A casket shell, on the other hand, refers specifically to the exterior part of a casket without the interior fabric and padding. An urn is used for storing ashes after cremation, which makes it significantly different from the concept of a grave box.

Understanding the role and definition of a grave box within burial practices highlights its importance in the context of funerary customs.
