Though badly damaged we can see the pendentive supporting the dome of a temple. Here pendentive is pyramidal(5 tiered) in form. This is the form of pendentive used extensively in Indian subcontinent only.
Pendentive: The concave triangular sections of vaulting that provide the transition between a dome and the square base on which it is set and transfer the weight of the dome.
Dated: 9-10th century CE or earlier.
