A network of corridors weave throughout the structure. The upper floor hosts a huge empty throne that overlooks the bonfire below, which can be lit with the Coiled Sword. Behind the fire is a small set of steps leading to an altar.
Could the stonework that supports this building be the same as that which forms the crumbled ruins around the Firelink encountered in another time? Though it may not be exactly the same, it is still probably located above the place where the Fire is linked. Perhaps this is evidence that Lothric and Lordran are the same as well, or somehow inexplicably linked.
There is a decrepit bell tower behind the Shrine that serves as the grave of Fire Keepers past.
