Here is what is reliably known and what can be understood in Jain terms:

1. Basic information

- Name: Shivmastu Samavsaran Jain Tirth (often listed as “Shri Shivmastu Samavsharan Shwetambar Jain Tirth”). ( jainmandir.org) - Location: Mandvi Rural area, near village Maska / Bharapar, Taluka Mandvi, District Kutch (Kachchh), Gujarat. ( shivmastumandvi.com) - Sampraday: Public listings describe it as a Śvetāmbara Jain tirth. ( jainmandir.org)

It is counted today among the important Jain spots around Mandvi along with “72 Jinalaya” and other Kutch tirths. ( wikimapia.org)

1. About its “history” (what we can and can’t say)

- It is a modern tirth, built in recent times by the Jain community of Kutch; it does not belong to the very ancient category like Shatrunjaya, Sammed Shikharji, etc. - Public sources that are accessible mainly give address and contact details, but do not clearly state: - the exact year of pratistha / opening, - the original main donors’ names, - the presiding Acharya / guru at the time of pratistha. ( shivmastumandvi.com)

Because of this, giving a precise chronological history (e.g., “built in year X by Y under Z Acharya”) would be guesswork, which is not proper in Jain dharma‑prachar. So we can only say with confidence that it is a recently developed Shwetambar Jain pilgrimage place in Mandvi region of Kutch, designed around the idea of the Samavsaran.

1. Why it is called “Samavsaran” Tirth

- In Jain Dharma, Samavasarana (Samavsaran) is the divine preaching assembly of a Tirthankar Bhagwan after attaining Keval‑jnan. It is open to all beings – devas, humans, tiryanch (animals, birds, etc.) – hence also called “Sarva‑sharna” (refuge for all). ( en.wikipedia.org) - Many modern tirths build Samavsaran‑style temples or models to help devotees visualize that sacred scene and do bhakti with the feeling: “I am sitting in Bhagwan’s Samavsaran and listening to divya‑dhvani.”

Shivmastu Samavsaran Jain Tirth follows this idea: - Architecturally / thematically focused on Samavsaran of Tirthankar Bhagwan. - Devotees visit mainly for darshan, prarthana, and to strengthen shraddha in Tirthankars’ divya‑deshna.

1. Spiritual importance (Dharma point of view)

Even though its physical history is modern, its spiritual base is ancient Jain tattva: - Smriti (remembrance) of Tirthankars’ Samavsaran. - Bhakti towards Arihant Bhagwan and respect for Chaturvidh Sangh. - Opportunity for: - Samayik, pratikraman - Swadhyay / pravachan - Pooja and darshan in a pavitra Jain tirth‑kshetra atmosphere.

Because reliable public information about dates and founders is limited, this is as much authentic history as can be stated without speculation. If you want more exact details (like year of construction, main trustees, pratistha mahotsav, etc.), the safest way is to contact the tirth office / management directly at Mandvi; they keep official records.
