The exterior of the Hazareshwar Temple is embellished with depictions of deities. The vedibandha (basal mouldings) has various ornamental elements including khura (hoof), kapotapalika (cyma recta), garggarika, karnika, grassapatta (a band of kirtimukhas or face of glory), plain patta, kumbha (pot), kalasha (pitcher), gaggarika (decorative motif comprising arrow between two spirals), and kapotapalika. On the jangha are bhadras (central offsets) on all three sides, with the space between them adorned with stambhas (buttresses) featuring motifs of peepal leaves and grassapatta. Rising above the jangha is the majestic shikhara (superstructure).
To the east, there is the main garbhagriha (sanctum sanctorum) accessible via the antarala (vestibule or antechamber). The dvarashakha (doorframe) of this sanctum is crafted by featuring multiple sections and adorned with sculptures of davarapalas (door guardians) and women holding kalashas (pitchers). Although the lalatabimba (lintel) of the doorframe displays a seated figure, its condition is not well preserved. Positioned above the lintel, the entablature showcases Natesha at the center.
The Hazareshwar Temple, also known as the Swarnajaleshwar Temple, houses a Shiva linga in the garbhagriha (sanctum sanctorum). This linga is positioned on a square yonipatta (womb-shaped base) and intricately carved with numerous smaller lingas. It is this unique feature of the linga, adorned with hundreds and thousands of lingas, that lends the temple its name, the Hazareshwar Temple.
The Hazareshwar Temple is comparatively a small temple in the Bijolia temple complex which comprises a mandapa (pillared hall), a shallow antarala (vestibule or antechamber), and a garbhagriha (sanctorum). It rests upon a deeply set vedibandha (basal mouldings), upon which the jangha (wall) is situated, supporting the shikhara (superstructure). Dedicated to Shiva, the Hazareshwar Temple is noted by the Archaeological Survey of India (ASI) for its architectural style resembling Bhumija (earth-born) architecture. An inscription discovered within the temple's mandapa indicates its dedication to Pashupata Shaivism.
The Mahakal Temple comprises twin structures referred to as Mahakal and Baijnath. Dedicated to Lord Shiva, this temple features Shivalingas in both sanctuaries. Facing west, the Mahakal Temple consists of a mukhamandapa, mandapa, antarala, and a garbhagriha in the southern direction, along with another garbhagriha in the eastern direction.
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).
