The central hall of the mahamandapa (pillared hall) in the Bisaldeo Temple is embellished with eight beautiful makara toranas (decorative arches or gateways flanked with crocodile-like mythical figures on each end). The toranas (decorative arched gateways) are crafted to give the illusion of doorways suspended by the extended snouts of two makaras (crocodiles) at each end.
Unlike other apsaras (celestial damsels) carved on the shaft of pillars, this particular figure is unique. She is crowned and holds a cup in her left hand, while her right hand holds something dipped in the cup. Similar images from the Harshnath Temple Complex depict a cup being held, symbolizing the nectar of bliss attained after the completion of tantric sadhana, while the fingers of the other hands are sometimes dipped into the cup. However, connecting this obscure image of a damsel with tantric connotations might lack substantial support.
The only significant depiction of the divinity of Shiva is found in the form of a four-armed portrayal of Bhairav on a temple shaft near the entrance of the temple, within the mandapa. It is the first religious image encountered upon visiting the temple. He is adorned with a serpent necklace, but other identifying attributes have deteriorated over time. His heavily bejewelled naked body reveals his genitalia.
The representation of a dancing Shiva or Natesha is depicted in the niche on the cornice above the pillar of the mandapa (pillared hall) of the Bisaldeo Temple.
On one of the pillars in the mahamandapa (pillared hall) of the Bisaldeo Temple is a short inscription which mentions the name of ‘Jogi Achpantadhaja’ or ‘Yogi Achintyadhvaja'.
The ceiling of the central hall or the mahamandapa (pillared hall) is of the nabhichchhanda variety, characterized by a band of five concentric overlapping circles decorated with lotus petals and other floral designs. The top of the ceiling is embellished with a full-blown lotus, complete with a padmakesara (stem-like) pendant.
In 1872, A.C.L. Carlleyle visited Bisalpur and provided the first known archaeological report on its temples under the supervision of Alexander Cunningham, the first Director General of the Archaeological Survey of India (ASI). His report includes a fully measured plan of the Bisaldeo Temple that was lithographed at the Surveyor General’s office in 1877.
