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.
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 lalatabimba (lintel) of the doorframe probably shows a Chaturmukha Linga, flanked and worshipped by devotees and maladharas on each side. The devotees are depicted with folded hands, a gesture of paying homage and respect. Next to these devotees, maladharas are carved holding garlands for the deity. Due to withering and the presence of heavy hairlocks, the other faces of the linga, besides the frontal one, are not clearly visible in the image. Nonetheless, the withered part of the linga resembles the other faces, hinting at the possibility of it being a Chaturmukha linga.
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 side walls (north and south) jaali or checkered windows are added which are topped by double chaitya arches. The rear of the garbhagriha has no window but it depicts chaitya arches.
On the south side of the linga, one can observe the face and bust of the deity. The deity has a heavy jatamukuta (matted crown) on its head and hairlocks coming down to the shoulders. The sringara (attributes) of all four faces of the Chaturmukha linga are distinct, highlighting the iconographic features.
The magnificently decorated sculpture of Nandi, positioned in front of the platform and oriented towards the mulaprasada (main temple), is truly impressive. Particularly notable is the hump of Nandi, adorned with an intricately coiled serpent, which gracefully encircles the hump, adding to the sculpture's beauty.
View of the entrance (east-facing) of the present temple structure. The doorframe is carved with figures at the bottom which have withered with time and can only be seen upon close inspection. The uttaranga (upper section of the doorframe) resembles a carved wooden roof. Dentil ornamentation breaks the monotony of an otherwise simple entrance.
