Northeast of the main gate of the fort is a cave where the air is extraordinarily cool. The cave, locally known as Jogida ni Gufa, was found and used by Buddhist monks thousands of years ago. It has Buddhist sculptures carved in stone that resemble the Bodhi Vriksha or Kalpavruksha and other Buddhist motifs. You also come across some beautiful Buddhist sculptures on the mountain on the way to the cave. Taranga Hills, 20 km from Vadnagar, on the Aravali range, harbours profound connections with Buddhism. The main idols enshrined in the Taranmata and Dharanmata temples are of Buddhist goddess Tara. Broken terracotta images of Buddha, four carved images of Dhyani Buddha on a stone plate, stone and brick walls inside rock shelters, etc. have been discovered from here.
