Suva

Suva's are usually shrines dedicated to Toa. Suva play an important part in the lives of Toa, as can be seen with the one in the Great Temple and the Toa Mata's Suva shrines on Mata Nui. Their primary function is to store Kanohi; a Toa can teleport masks to and from a Suva when they are needed. Little is known of the mechanics involved in them, but it's been confirmed that they physically store Kanohi and not in a form of energy like when they're summoned.

Other beings such as Turaga can use Suva, however, and there are multiple uses for Suva.
