Dharanendra Parshwanath is not a separate “location” by itself in the 108 Parshwanath list. Dharanendra (the serpent guardian) is a protective figure often shown with Parshwanath Bhagwan in many Parshwanath temples.

A well-known 108 Parshwanath tirth where Dharanendra is venerated with Parshwanath is Shankheshwar Parshwanath in Gujarat (Shankheshwar, Patan district). There you find the Parshwanath idol along with Dharanendra and Padmavati in the temple complex. You can read more about Shankheshwar Parshwanath here.

If you’re looking for other 108 Parshwanath sites where Dharanendra is present, many temples dedicated to Parshwanath include Dharanendra as part of the temple’s iconography. The Shankheshwar temple is the most prominent example often referenced in the “108 Parshwanath” context.
