RE: Cornerstones in Mireuksa Temple, Iksan City

Having the ancient architecture, the people knew a lot about the foundation of the buildings and stability, it was clever to use cornerstones to make sure that the building will not sink in the ground with the time, when the soft soil gives away then the whole building would be destroyed. The stones are massive and well polished even in old time, that must be hard and time consuming work :)
