The temple walls have been constructed using dressed stone masonry with mortar. As is common in temples constructed in the same period, a double-wall system would have been followed : the wall comprises two layers of stone with the cavity between them being filled with rubble, so that the wall resembles a sandwich. The thickness of the wall ranges from 60 cm to even a meter thick in some places. Along the wall surfaces, one can see crude stone blocks protruding out at regular intervals. These large stones are known as through-stones or bond stones. They span the whole width of the wall and help to structurally lockthe two layers of walls together. As you walk around the pradakshina, notice how the bond stones are critically placed at the juncture of two beams, allowing for an efficient transfer of load onto the stone walls. These through-stones are also visible on the small stretch of the old temple compound wall to the North of the main shrine.
