Here are some of the most famous Parshwanath (Parshvanath) temples:

• Sammed Shikharji (Shikharji), Jharkhand — the sacred hill where many Jain temples cluster; Parshwanath is one of the principal Mulnayaks here and the site is a major pilgrimage for both Digambar and Svetambar Jains.
• Panchasara Parshwanath Derasar, Patan, Gujarat — a renowned Śvetāmbara temple of Parshwanath with historic significance dating back to early centuries.
• Parshwanath Temple, Khajuraho, Madhya Pradesh — the largest Jain temple among the Khajuraho group, dedicated to Parshwanath.
