English: The Mamleshwar temple, also known as Amareshwara or Amaleshwar mandir, is a complex of historic temples located in Godarpura across from Mandhata, on the southern bank of the Narmada river. This temple hosts the second Jyotirlinga of Omkareshwar, and one of the only twelve on the Indian subcontinent. Like the other Jyotirlinga on the Mandhata island, this complex too is from the 11th-century, one abandoned after the destruction during the Sultanate era, then rebuilt by Holkar-Maratha Hindus in the 18th-century. The contributions of Rani Ahilyabai are of particular note.

The site consists of one main temple which hosts the Jyotirlinga, along with subsidiary shrines that surround it. The temple mandapa has walls with panels of Shaiva, Vaishnava and Shakta artwork. Similarly the doorway to the sanctum is beautifully carved with Hindu art. The Mamleshwar temple has the Halayudhastotra inscriptions, which the Indologist and epigraphist Richard Salomon calls, "a little known masterpiece". It is likely that the much cherished Hindu text and famed Devi Mahatmya – the Sanskrit text recited during Durga Puja – was composed in the Mamleshwar temple complex and the Hindu temples on the Mandhata island.
