Dvarapalas carved on the either sides of the pillars of the rock - cut temple. There are 12 Vishnu Sculptures present on the rock surface and a base of lingam with 24 pits is present inside the
Garbhagriha. Archeologist and Historians say that the 24 pits in the base could have represented that the 12 structures of Vishnu present outside are part of the
24 Names of Vishnu and are the most important ones. The complete 24 forms together is the Supreme god Vishnu in the main chamber in the form of a pedestal (Representing Vishnu who also has a form of formlessness). There is a huge Granite foundation carved with steps to reach the Shrine dedicated to Maha Vishnu, the Foundation consists of several carvings of the mystical animal
Yali in different form with non- mystical animal like elephants together. The other portions of
Narthamalai houses the 8th century Jaina Abode, the Aluruttimalai Jain Caves dedicated for people who believe in
Jainism. Shrine for
Shiva was surrounded by eight shrines, out of which six are present today. The main shrine faces west and the sanctum houses the image of
Lingam, the aniconic representation of Shiva. The walls of the sanctum are plain, unlike later Chola temples that have niches to house different images. The sanctum is approached through an Arthamandapa – a hall supported by pillars. The pillars are ornamental, rectangular shaped on the bottom and the top, and octagonal shaped in the middle. The
vimana, the shrine over the sanctum has a semi-spherical shape, having four storeys. The sanctum is guarded by
Dvarapalas on either sides. The inscriptions are made on the base of the Dvarapalas. There are also two rock-cut caves, one of which houses twelve life size sculptures of
Vishnu. ==Significance==
