Favissa

A favissa is a cultic storage place, usually a pit or an underground cellar, for sacred utensils and votive objects no longer in use.

[3] During the time of ancient Rome, the term favissa referred to a cylindrical underground storage space, specifically designed to house votive objects.

The Roman favissa served a similar purpose as the Greek treasury, functioning as a dedicated space for storing valuable offerings and dedicatory items.

[4][5] An example of such a structure is found in the Favissae Capitolinae, designed to house all the votive objects from the Temple of Jupiter Optimus Maximus located on Rome's Capitoline Hill.

As time passed, the use of favissae gradually diminished, to the extent that their significance had been completely forgotten by the imperial era.
