Yes — if you mean Delwara village/town in Rajsamand district, Rajasthan, then it is a Jain Maha Tirth and is different from the famous Dilwara temples of Mount Abu. Delwara was traditionally known as “Devkul Patan Nagri”, and old tradition says it once had more than 1,500 temples, including over 400 Jain temples. ( jainmandir.org)
The Jain history of Delwara is linked with its long sacred past and many temples. Jain temple records describe it as an important pilgrimage place in Delwara, Rajsamand, with major temples such as Shri Rishabh Dev Jain Shwetamber Mandir and Shri Parshvnath Jain Shwetamber Mandir. ( jainmandir.org)
A traditional account of Shri Delwara Tirth says that the temple was repaired and reconsecrated in Vikram Samvat 1378 by descendants of Sheth Gosan and Bhimana, who belonged to Mandor, and that there is also a Digambar Jain temple nearby. ( jainknowledge.com)
