"From the artifacts discovered by archeologists at San Thome, one can infer that the temple should have existed elsewhere and most probably it existed at San Thome beach . . . because remnants of the old temple were discovered at San Thome beach. In 1923 when archeologists conducted excavations at San Thome cathedral they discovered inscriptions and statues. The inscriptions indicated a temple. [. . .] Saint Arunagiri Nathar also mentions that Kapaleeswara temple existed by the side of the beach. . . . Hence, in conclusion, one can state that the old Kapaleeswara temple was destroyed by Portuguese in the fifteenth century and was built in its present place by Nattu Nayiniappa Muthaliar and son in the sixteenth century."
