The pillar on the north end of the antarala has an inscription in Brahmi script with Gupta letters playing an important role in dating the foundation of the temple. The inscription is carved below a full-blown lotus. However, the surface of the pillar has deteriorated and the letters are not clear, making it difficult to discern the meaning of the inscription. Nevertheless, one can observe that the inscription comprises twelve lines. The last three lines appear distinct in their letters and style compared to the upper part of the inscription. The first three lines of the inscription discuss the Shiva linga and the temple.
View of the mulaprasada (main temple) from the southwest. The garbhagriha, unlike the mandapa exterior, shows some decoration on its façade. The garbhagriha stands on base mouldings with jaali (checkered) windows and chaitya arches. It has a simple latina-type shikhara (spire) with niches topped by udgama pediments (pediments with interconnected chaitya dormers) which look like miniature shikaras. At the apex, an amalaka is placed topped by bijapuraka (citron fruit).
The garbhagriha, or inner sanctum, of the temple, is a small and dimly lit chamber currently housing a sculpture of the Goddess Adi Shakti. The only decoration visible is at the entrance of this space: the T-shaped doorframe which has multiple decorated shakhas (vertical mouldings on the door jamb). The bottom of the shakha depicts the river Goddess Ganga and Yamuna which are presently in a bad state of preservation.
The mandapa (pillared hall) in the Shiva Temple of Charchoma is a rectangular hall featuring a stone platform at its centre. Four pillars stand at each corner of the platform, presently covered with decorated cloth pieces. The pillars are topped with brackets supporting the ceiling which follows the trabeated system of constructions.
The side walls of the garbhagriha have windows which are topped by double chaitya arches. The lower chaitya arch depicts the bust of a deity flanked by two celestial beings. The upper chaitya arch shows a grassamukha.
Southeast view of the mulaprasada (main temple). Comprising a mandapa (hall), antarala (vestibule or antechamber), and a garbhagriha (sanctum sanctorum) on its plan, the temple has a simple elevation with minimal decoration. Outside the main temple, there is a yajnakund for performing yajna and havan (fire rituals).
The jangha of the garbhagriha depicts a bhadra which is carved with the figure of deities. Apart from that the only decorative motif visible on the walls is a horizontal band of kirtimukha. Above the jangha, a varandika (shoulder) is carved which is made of mouldings including gaggarika and kapotapalika with a chaitya arch motif.
One of the mouldings on the vedibandha of the garbhagriha is the kumbha which is carved with figures of deities, apsaras, mithunas and maithunas. Here, both the mithuna and maithuna imagery can be seen. Mithuna represents a couple embracing each other where the male figure is softly pressing his partner’s breast. The maithuna, next to the couple, shows four figures engaged in amorous activities.
The garbhagriha presently in its elevation consists of the original vedibandha and jangha. The vedibandha comprises various mouldings and the jangha has a bhadra (central offset) and karna (corner projections). The jangha on the right of the temple, as seen in the image, is devoid of any sculpture on the bhadra niche but the other two sides are carved with the figures of deities.
The mandapa of the temple is open and has only base mouldings belonging to the old structure. It now has a smooth tile floor and there are two broad stairs at the end which lead to the main sanctum. A black stone figure of nandi facing the sanctum is placed on one of the stairs. The front wall of the main sanctum is also a new structure with a metal gate to enter the sanctum. The udumbar (threshold) of the sanctum has the original part of the temple which now is the only decorative element left of the entire façade.
