Kadasiddheswara Temple is one of the monuments in Pattadakal that dates back to the 7th century. Compared to the other temples the sculpture of Kadasiddheswara Temple is less ornamented. The architecture of Kadasiddheswara Temple is known for its experimental features. This fact is evident from the axial expansion of the temple plan and the superstructure. As is the norm with the Hindu temples the Kadasiddheswara Temple faces the eastern direction.

According to the architectural plan this Pattadakal temple was to comprise of a garbhagriha where the presiding deity resides. A Shiva linga has been placed here. A rectangular mandapa, astylar and a mukha-mandapa consist of the main shrine. Sculpted images of dwarapalas are to be found beside the mandapa doorway. These are decorated with five worn out bands or sakha.

A plinth with five mouldings has been used to build Kadasiddheswara Temple. The sculpture of Kadasiddheswara Temple is not as profuse as the other Pattadakal temples. In fact the wall surfaces are completely plain except for the friezes bearing the sculpted images of the ganas. The stone sculpted ganas are seen here with garlands in their hands. The experimental superstructure is reminiscent of the rekha-nagar style. This style of architecture was prevalent in North India. It has a curvilinear profile with a basic sukanasa projection. This bears Lord Shiva in a dancing posture alongwith Goddess Parvati within the chaitya-arch.

It is the outer walls of the sanctum where one will come across few sculptures that include the carved figures of Ardhanariswara, Lord Shiva and Harihara. The doorframe of the sanctum has pilasters that have been set amidst the ornamental sculptures of bands where Shiva and Parvati are shown seated at the center of the lintel. They are flanked by Lord Vishnu and Brahma on either side. The figures of river goddesses and attendants are also found below the sakhas.

It is the simplicity of the architecture and sculpture of Kadasiddheswara Temple that makes it appealing.
