subshrine
A subshrine is a small shrine or altar that is subordinate to a larger, principal shrine. These smaller structures are often found within the grounds of a major religious site or temple complex. They may be dedicated to a secondary deity, a specific aspect of the main deity, or serve as a memorial to a particular individual or event. The precise function and significance of a subshrine can vary greatly depending on the religious tradition and the cultural context in which it exists.
In some traditions, subshrines might house relics, offer a place for individual prayer and devotion separate
