An archaeological study in 2010 revealed that the layout of the rock-cut caves in the temple is similar to that of other rock-cut temples such as the Rockfort and Pechipalai cave temple. The unfinished caves in the temple, along with the lower cave temples in Tiruchirappalli and Tiruparankunram, each have a shrine for Shiva in the east and Vishnu in the west, separated by a central bay between them.
