3-D GPR imaging of central pillar of the Mireuk stone pagoda in Korea

Mireuk Pagoda is a very important national treasure which is known to be constructed during late Baekje kingdom about 1,500 years ago. To investigate the inner structure of central pillar of this stone pagoda, 3-D GPR and tomography imaging was applied. During this geophysical survey, we could find and define a small room in the pillar. Since full coverage was available in the radar tomography, we could obtain very accurate image of this empty room. By the disassembly of the cover stone of central pillar after this investigation, we could find great historical remaining in this room. The findings include golden jars containing relics of Buddha and written documents explaining construction history of this pagoda.
