@slowwalker, That'a well introduction of national treasuries in Keumsan-sa Temple. First black stone stupa remarkable design indeed. I'm wondering to see it how about creativity of architectural technique. Also those temple has long historical story. Some of patterns embossed to stones.

Korean stupa has its own unique style

Yep...I see it now better. Second Lotus stupa has more impressive look than first to me. Wow...Final stone lantern brilliant looks to me now. It has gorgeous patterns. Actually we're luckily steemians to see those four models of stone stupas survived from war and with your guidance.
