The mandapa (pillared hall) and mukhamandapa (front porch) of the Undeshwar feature elaborate moldings and low walls that uphold intricately carved kakshasana (seat back). Niches on the walls of the mukhamandapa and mandapa are adorned with carvings depicting deities such as Kartikeya, avatars (manifestations) of Vishnu, and the ashta dikapalas (deities representing eight cardinal directions).
Varuna is depicted on the kakshasasna (seat back), of the Undeshwar Temple, alongside his vehicle, the Makara (crocodile). He holds a pasha (noose) in his upper right hand and a pushpa (flower) in his upper left hand. In his lower left hand, he carries a kamandalu (water pot), while his lower right hand is extended in the Varada hasta (hand gesture of conferring a boon) gesture.
Chamunda is depicted on the exterior wall of the antarala vestibule or antechamber) of the Undeshwar Temple, serving as the first figure encountered by devotees during the parikrama (circumambulation). Standing atop a human body, she is accompanied by two attendants and an animal. Although she possesses multiple arms, many of them are damaged. In her upper hands, she holds a sarpa (serpant), partially obscured by her jatamukuta (crown of mattered hair). Her intact right arms hold a damaru (double-headed drum) and a trishula (trident), while her left intact hands grasp a khatvanga (staff with a skull) and a bowl. She touches her lips with the finger of her left hand. At the bottom left, a seated figure is depicted holding a bowl, suggesting he is drinking from it. It is conceivable that one of the broken left hands of the goddess was carrying a munda (severed human head). The presence of the seated figure with a bowl implies he is drinking blood dripping from the severed head. Chamunda is portrayed with a skeletal body, and her belly cavity contains a scorpion. Her lower body is covered with a loin cloth.
The passage from the mukhamandapa (front porch) leads to the mandapa (pillared hall), marked by two detached busts of Sadashiva at both sides of the entrance. Each bust portrays Sadashiva with three faces.
To the south of the mandapa (pillared hall) lies a shrine with an intricately carved, multi-shakha (vertical bands or architraves) doorframe. The doorframe contains niches adorned with Shiva and his manifestations, Matrikas and Ganesh. The lalatabimba (lintel) is covered in white paint, obscuring its details. In the garbhagriha (sanctum), a Shiva linga is placed.
The mukhamandapa (front porch) of the Mahakal Temple features a kakshasana (seat backs) adorned with niches housing divine figures, including deities like Brahma and Kaumari. Interwoven among these divine figures are depictions of ascetics, musicians, and surasundaris (celestial damsels).
The garbhagriha (sanctum sanctorum) of the Mahakal Temple on the east is a square, simple, dimly lit chamber which has a Shiva linga at the center. The Mahakal Temple is a living temple where people come to worship regularly Shiva lingas in both the garbhagrihas (east and south).
The front view of the Mahakal Temple shows that the temple can be reached from the west. It has a small mukhamandapa (front porch) with a flat roof. The entrance to the mukhamandapa is adorned by sculptures of Ganesha and Bhairava on either side.
To the left of the mukhamandapa (front porch) of the Mahakal Temple, one can observe a standing statue of Ganesha. This depiction shows him with four arms, carrying a kamandalu (water pot), akshmala (rosary), another object and a bowl filled with modaks (a form of sweet with stuffing).
To the right of the mukhamandapa (front porch), of the Mahakal Temple, entrance stands another male deity statue. This deity, depicted in a standing posture, has several arms, now damaged. Adorned with a jatamukuta (a crown of matted hair) and sporting a beard, he is accompanied by an attendant depicted at the base, while gandharvas (celestial beings) are carved at the top corners.
