Omkareshwar located in Madhya Pradesh, on the Mandhata hill on the banks of the Narmada is one of the 12 revered Jyotirlinga shrines of Shiva. It is located at a distance of about 12 miles from Mortakka in Madhya Pradesh. 

The river Narmada branches into two and forms an island Mandhata or Shivapuri in the center. The shape of the island resembles that of the visual representation of the Omkara sound, Om. There are two temples here, one to Omkareshwar and one to Amareshwar.

Legend has it that the Vindhya mountain prayed to Shiva - Omkareshwara and was blessed here. Legend also has it that upon the request of the Devas, the Shivalinga split into two, one half being Omkareshwara and the other Amaleshwara or Amareshwar. King Mandhatha of the Ishvaku clan is believed to have worshipped Shiva here.

Govinda Bhagavatpaada, the guru of Sankaracharya, is believed to have lived in a cave here.

The temple can be reached by ferry from the banks of the river. The Omkareshwar temple built in the Nagara style is characterized by a lofty shikhara. There are also shrines  to Annapurna and Ganesha here.
