Palitana is one Tirth: Shatrunjaya (Palitana Tirth).

Within this single Tirth, there are traditionally said to be about 865 Jain temples (derasars) on the hill, arranged in 9 main enclosures (tunk/took). Counts can vary because some include many small shrines and subsidiary temples, so you may also see figures around “800+.” Steps to the summit are about 3500.
