These two octagonal stupas displaying the same overall size and style were built as tombs for Buddhist monks and enshrine the monks’ remains (sarira). They are positioned from east to west to the north of the Buddhist sanctum at Manghaesa Temple. The dilapidated eastern stupa was restored in November 1960. The stylobates supporting the main bodies of the stupas consist of three layers of stones: The bottom layer is octagonal in shape, and supports a stone engraved with lotus flower patterns; the middle layer is composed of a high octagonal stone and a three-stepped supporting stone; and the upper layer is beautifully engraved with a double-design of a lotus flower with sixteen petals. All the surfaces of the main body are carved with a window frame design, while its corners are carved with pillar patterns, and its four faces are engraved with a door design. The eaves and angle rafter of the roof stone are horizontal, and each end has a hole to hold a wind chime. The finial parts from both stupas are missing but some parts are kept separately. Although the technique and overall formation of the stupas are rather basic on the whole, they exhibit a well-proportioned structure.
