The antarala (vestibule) of the temple has four pillars. It is a rectangular plain passage that connects the mandapa (pillared hall) with the garbhagriha (sanctum sanctorum). This section of the temple structure dates to the Gupta period, as evident by a Gupta Brahmi inscription engraved on one of the pillars (on the right). The antarala leads to the garbhagriha which has a beautifully carved T-shaped door frame, one of the characteristics of Gupta-period temples. The doorframe of the garbhagriha has multiple shakhas, which are carved with figures of the river goddesses on each side at the bottom and dwarf figures and floral decorations above them. The antarala leads to the garbhagriha which has a beautifully carved T-shaped door frame, one of the characteristics of Gupta-period temples. The bottom of the shakha depicts river goddesses Ganga, on Makara, and Yamuna on Kachhappa, with their attendants. Above them, beautiful undulating creepers are shown. The shakha next to it shows standing dvarapalas, on each side, holding a weapon and flanked with dwarf figures performing different activities such as dancing, singing, and playing musical instruments.
View of the main temple structure 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 last shakha, depicting standing dvarapalas on each side, also showcases dwarf figures above. These dwarfs are depicted playing musical instruments, with one of the dwarf figures shown playing the drum.
The pillars of the antarala have a square base. The middle square shaft is carved with the half lotus medallion. Above this medallion, the shaft turns circular, topped with an amalaka, and a plain square abacus.
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 doorframe of the garbhagriha has multiple shakhas and each shakha is decorated with a specific pattern. The bottom of the shakha depicts river goddesses Ganga, on Makara, and Yamuna on Kachhappa, with their attendants. Above them, beautiful undulating creepers are shown. The shakha next to it shows standing dvarapalas, on each side, holding a weapon and flanked with dwarf figures performing different activities such as dancing, singing, and playing musical instruments.
The mandapa of the temple is a rectangular hall with simple and plain outer walls. It has a flat roof. There are no decorative elements present on the walls except the flanking chhajja supporting the roof.
The jangha (wall) of the garbhagriha (sanctum sanctorum) has a broad floral scroll that runs across all three walls and divides the wall into upper and lower parts. On the rear wall, this band is topped by two beautiful chaitya arch motifs. At the apex of the arch, a grassamukha is shown emitting the flowers which are decorating the chaitya arch.
The garbhagriha of the Charchoma Shiva Temple presently houses a Goddess image, probably Parvati, locally revered as Adi Shakti. The sculpture is dressed in such a way that the attributes and iconography of the Goddess sculpture are not discernible. There is a trident made of metal which is installed near the sculpture. Upon closer inspection, carvings of figures can be seen on the sides of the Goddess. But the figures are damaged, and their details are rubbed off.
