Jain architecture is exemplified in their rock-cut caves and stupas found in regions like Mathura, Bundelkhand, Madhya Pradesh, and Orissa, notably featuring structures like the Udaigiri and Khandagiri caves. These caves, mainly excavated for ascetic retreats, differ from Buddhist viharas in layout, with smaller, simpler cells designed for ascetic practices. The architecture illustrates significant features such as intricately carved friezes and historical inscriptions, with the peak of Jain architectural excellence occurring in the 11th and 12th centuries AD.
