The ceiling beam in the sanctum depicts an array of warriors marching towards the right on its side, while the lower face of the beam is richly carved with vegetation foliage.
A four-armed Vishnu is depicted seated in the lalitasana posture. He carries a mace and a chakra in his upper right and left hands, respectively, while the lower right and left hands hold a mala and possibly a citron, respectively.
The trio of Ganesha, Surya, and Chandra is one of the several loose sculptures that were affixed on the later structures at the site. The three figures may have once been part of a larger panel depicting the nine heavenly bodies or the navagraha. While the dancing Ganesha is four-armed, the images of Surya and Chandra have only two arms, broken in both cases. The erect uplifted posture, or the samabhanga, of Surya contrasts with the dynamic posture of Ganesha and the tribhanga posture of Chandra. Both Surya and Chandra have broken heads but can be identified through the boots of the former image and the depiction of a crescent behind the neck of the latter.
Close to the Harshnath Temple complex lies the Bhairon shrine featuring a semi-iconic rock revered locally as the Harsha Bhairon. He is believed to be a manifestation of the folk hero, Harsha, who decided to settle at the hill to worship Shiva. He is believed to have been blessed by Shiva to be worshipped as Bhairon on the hill. Several 10th-century CE sculptures are fixed on the walls of this complex. Today, the Bhairon shrine is the epicentre of pilgrimage to Harsha Hill and is considered as the family deity of several local communities.

The loose architectural fragments in front of the Harshnath Temple include a pillar with a band of dancers and musicians, a four-armed image of Shiva, which was once part of a devakostha niche, featuring a snake and a trident in the two hands above and another niche of smaller size depicting Bhairav holding a sword and a skull-headed spear.
The shrine of Harsha Bhairon is now an epicentre of spiritual activities at Harsha Hill. This late medieval structure has an enclosure wall, upon which sculptures are affixed both inside and outside.
