What type of religious structure originally meant to house relics?

The type of religious structure originally meant to house relics is called a "reliquary." Typically crafted from precious materials, reliquaries serve to protect and display sacred objects, such as the remains of saints or items associated with them. They are often found in churches and cathedrals, highlighting the significance of the relics within the faith community. Over time, reliquaries have evolved in design and function, but their primary purpose remains the veneration of holy relics.
