Abstract

The ground investigations for a historical site of archaeological importance are usually a labor intensive and time consuming process. Exploratory diggings are most commonly employed to know about the buried artifacts or construction features. Many a time important features are not documented because such features are not easily accessible or the approach involves disturbance to the monument. A study was made with Ground Probing Radar (GPR) at Taj Mahal, one of the most cherished monuments of the Mughal period. The GPR techniques are comparatively new for the studies of foundation features of such monuments. In this paper, the results are presented from a GPR investigation with 100 and 200 MHz frequency antenna. Important features detected from GPR profiling near the boundary wall and on the Mausoleum floor are discussed. The location of the foundation wells and stone pinning etc. was correlated with the borewell data. Some features identified by GPR, however, could not be confirmed due to intricate location of the subsurface features. The findings show that the GPR techniques with a large spectrum of the antenna frequencies can be used to investigate the details of subsurface features at historical sites.
