The mandapa (pillared hall) of the Hazareshwar Temple is a small square open hall that stands on a low base, supported by four pillars positioned at its corners. These pillars feature square bases adorned with depictions of deities. The shaft of the pillars is intricately carved with male deities, musicians, dancers, and surasundaris (celestial damsels). Transitioning into an octagonal shape, then into sixteen facets and circular, the shaft culminates with an abacus supporting bharavahaka (load bearers) brackets, which in turn uphold the lintel. The mandapa's ceiling, square in shape, is exquisitely carved. There is an idol of Nandi housed at the centre of the mandapa.
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.
