Lord Kartikeya was describing various important Shiv Lings in his narration in Kashi Khand (Chapter 68). 

Aadi Mahadev

In Satya Yug, in response to devout prayers by Devas and Rishis, one Ling emerged from the Bhoomi and manifested itself. This came to be called  Mahadev Ling.  This Ling gets the credit of making Kashi a Mukti Kshetra (region free from bondage). A person who peforms pooja and archana with sincere devotion at this temple will reach Shiva’s abode after death, even if he happens to die in any place other than Kashi.   

A devotee who sincerely prays to Lord Mahadev in Kashi, gets the punya equivalent to praying all Lings available in the entire world. A person who performs pooja at least once at Mahadev temple, will find a place in Lord Shiva’s abode after death (Kashi Khand, ibid).

Special importance is attached to the offering of Yagyopaveeth (Sacred Thread) at Mahadev temple on Chaturdasi Day after Amavasya during Shravan Month (July-August) (Kashi Khand, ibid).

Presently the temple is known as Aadi Mahadev Temple.
