- These structures typically enshrined a stupa, and later, they also housed images of the Buddha. - The earliest surviving chaityas date back to the late first millennium BCE.
- Chaityas were built across the country, either with bricks or carved from rock. However, it is believed that wooden chaityas existed even earlier.
- The largest excavated brick chaitya hall is located at Guntapalli in Seemandhra.
