The main shrine is of a mandapa of four pillars supported on the heads of lions, so commonly seen in Pallava architecture. The walls on three sides clockwise show a pralambapada Buddha, Avalokitesvara and the Buddha preaching at Sarnath, all seated in shrines.The detachable stupa above this platform encloses a seated figure of the Buddha in bhumisparsa mudra. The harmika of the stupa comprised twenty-seven discs and is topped by a kalasa. It is a unique representation of a stupa influenced by South Indian tradition. Though the exact location of its find remains unknown it was possibly created in an around Nagapattinam where Buddhism prevailed.
