This
temple is important for its architectural variation
from the main Orissan architectural genre. The temple
is open to the sky (hypaethral). Only four such temples
have been found in India and Orissa, has the distinction
of having two such temples.
The Sixty
Four Yoginis temple at Hirapur is a circular enclosure
with a narrow doorway to the eastern side. There
is no roof over the enclosure. The round wall is
made out of locally available Khondalite or Sand
Stone and the foundation is with Laterite stones.
Inside the temple there are 60 niches and in every
niche there is a figure of a Yogini. The other four
Yoginis who were perhaps housed in the Pillared
Mandap in the centre of the Shrine cannot be seen
now.
