The concave roof-end tile, which seals the end of a row of concave roof tiles, comes in two types: one with a jaw and the other without one. The arabesque-designed tile is the most common, followed by those with designs of honeysuckle or grass and flowers. The typical arrangement of designs features vines stretching out from both ends and crossing at the center symmetrically. The blank space left between the simplified stems and designs gives a sense of stability. Concave roof-end tiles of this type were also discovered in the Sacheonwangsa Temple site and the Wolseong moat. The tiles are estimated to have been produced between the years of 660 to 680.
