There are two of these objects in the game. One is used to open the door in the Roofed Passage to access the Garden Shed and, ultimately, the Courtyard. Later on when you acquire the second Stone and Metal Object by combining the Stone Ring with the Metal Object, you can remove the first one from its place in the Roofed Passage. You must then use both objects on the metal gate behind the stairs in the Main Hall to access the Altar.
