A site of pilgrimage situated on the southern bank of the holy river Narmada; it has been alluded to in Matsyapurāṇa (Matsyapurana) and Kurmapurāṇa (Kurmapurana). The piety obtained at this sacred site from ablution, charity, feasts and making sacramental offering to the manes has been described in Purāṇas. It is assumed that there is an idol of Śiva (Shiva) situated here because Matsyapurāṇa explicates the rites of collecting water from the site of Tryamvaka-Śiva to cook the oblation for the offering to the manes—a meal of sunned rice boiled in milk with ghee and sugar. It is quite likely that ancient Aṅkola is actually Ankleshwar of today, located in the current Bharuch (formerly Broach) district of Gujarat. Cunningham has identified the region of Arikaleshwar, located on the left bank of Narmada, with Akrūreśvar (Akrureshwar); this place is also known as Ankottak. And this could also be the Aṃkola site. On the other hand, according to S.G. Kantawala, there is a celebrated sacred ground called Ankol situated in the Nikora region, a mile away from Ladva on the northern bank of Narmada. Hence, this could also be the sacred place of pilgrimage, Aṅkola, alluded to in Purānas.
