A reliquary is an object used to store and display religious relics. It can be a CHEST, SHRINE, or arca, all of which are terms used to describe a reliquary. A CHEST is a box-like container with a lid, usually made of wood or metal, and is often decorated with carvings or paintings. A SHRINE is a structure or place dedicated to a particular deity or saint, and is often ornately decorated. An arca is a type of reliquary that is typically made of precious metals and is often decorated with jewels.
