This is a detailed view of the intersecting triangular ceiling construction utilized in the western auxiliary chamber of Anak Tomb No. 3. Three layers of supporting stones were installed in parallel to protrude over the wall, and two additional layers of triangular supporting stones complete the ceiling. The top two layers of triangular supporting stones can be seen in this image. A stepping architectural technique called caisson ceiling or spider web ceiling was utilized to fill the void. This method of ceiling construction is referred to as an intersecting triangular ceiling or caisson ceiling. This caisson ceiling construction method originated in ancient Mesopotamia and was prevalent in Greece. It passed through Western and Central Asia and spread throughout Koguryo. This style can be regarded as a valuable proof of cultural exchange between the East and the West. A square cap was installed in the center to complete the ceiling. A blooming red lotus can be seen in the center of the stone.
