Nageshvara Jyotirlinga is one of the 12 Jyotirlinga shrines mentioned in the Shiva Purana. Nageshvara is believed to be the first Jyotirlinga on the earth. It is located in Dwarka , Gujarat ,India.
Nageshwar was believed to be known as 'Darukavana', which is an ancient epic name of a forest in India.According to the first legend, 'Balakhilyas', a group of dwarf sages worshipped Lord Shiva in Darukavana for long a time.
To test their devotion and patience, Shiva came to them as a nude ascetic wearing only nagas [serpants] on his body. Wives of sages got attracted to the saint and went after him, leaving their husbands behind. Sages got very disturbed and outraged by this.They lost their patience and cursed the ascetic to loose his linga [one of the limited meanings is Phallus, but it has has a deeper theistic symbolism].
Shiva linga fell on the earth and the whole world trembled. Lord Brahma and Lord Vishnu came to Lord Shiva, requesting him to save the earth from destruction and take back his linga. Shiva consoled them and took back his linga. Lord Shiva promised his divine presence in Darukavana as 'jyothirlinga' for ever.

As per Shiv Mahapuran, once Brahma (the Hindu God of creation) and Vishnu (the Hindu God of Protection and Care) had an argument in terms of supremacy of creation. To test them, Shiva pierced the three worlds as a huge endless pillar of light, the jyotirlinga.
Vishnu and Brahma split their ways to downwards and upwards respectively to find the end of the light in either directions. Brahma lied that he found out the end, while Vishnu conceded his defeat. Shiva appeared as a second pillar of light and cursed Brahma that he would have no place in ceremonies while Vishnu would be worshipped till the end of eternity.
The jyotirlinga is the supreme partless reality, out of which Shiva partly appears. The jyothirlinga shrines, thus are places where Shiva appeared as a fiery column of light .
