Ahilyabai was a great pioneer and builder of Hindu temples. She built hundreds of temples and Dharmashalas across India. Her greatest achievement was to rebuild the Kashi Vishwanath Temple in 1780, which was dedicated to Shiva; the presiding deity of the city of Varanasi, one of the holiest Hindu sites of pilgrimage, that had been plundered, desecrated, demolished and converted into Gyanvapi Mosque on the orders of the Mughal emperor Aurangzeb in 1696.
