A twenty-foot-wide moat divides this shrine into northern and southern halves. In the north half, two large stone pillars flank an altar in the form of a plain stone block. A few coins lie on the altar. Above and behind the altar looms a huge symbol made from beams of driftwood, fixed in an X-like shape on the wall. A single stone door leads westward from this part of the room.
In the southern half of the room, two ten-foot-wide channels run along the east and west walls of the shrine, spilling out through low culverts to the south. Two more pillars stand here, and a low stone bridge leads across the dividing channel to the altar and the northern part of the room.
