Junagadh (Girnar) tirth is one of the most revered Jain pilgrimage sites. Here is a simple, authentic overview:

• Where and what: Girnar hill near Junagadh, Gujarat, hosts a group of Jain temples on multiple “tonks” (levels). It is considered a Mahatirth in Jainism because of its long history and sacred events connected with Tirthankaras, especially Neminath (Arishtanemi). ( jainknowledge.com)

• Key significance: The 22nd Tirthankar, Neminath, is closely linked with Girnar. He is said to have adopted renunciation there, attained omniscience (Keval Jnana), and ultimately Moksha (nirvana) from the highest peak of Girnar. His wife Rajulmati is also part of related legends on the hill. This makes Girnar one of the principal Jain pilgrimage sites for both Śvetāmbara and Digambara communities. ( jainknowledge.com)

• Main temples and tradition: The main Swetâmbar temple at Girnar’s primary tonk is a central shrine, with other tonks housing temples of Sambhavnath, Parshwanath, and various other shrines. The site is traditionally described in Śvetāmbara literature; Digambar traditions also honor Girnar as a sacred Jain tirth within the broader Girnar complex. ( jainknowledge.com)

• History in brief: Girnar’s Jain heritage is tied to ancient to medieval times, with temple renovations and patronage by various kings and Jain communities recorded across centuries. The Neminath temple on Girnar was constructed during the medieval period (approx. 12th century CE, with later renovations), reflecting continuous Jain devotion on the hill. ( jainknowledge.com)

• Modern context for visitors: The Girnar tirth remains a living worship site with temples accessible to pilgrims; the ascent involves a long stairway up the hill to reach the main shrines. Different Jain traditions may emphasize slightly different legends or temple hierarchies, but the core theme is the veneration of Neminath and the spiritual ascent of the soul. ( jainknowledge.com)
