- This may contain bodily remains of the Buddha or his followers, or things they used, as well as precious stones, and coins.
- This box, known as a relic casket, was covered with earth. Later, a layer of mud brick or baked brick was added on top. and then, the dome-like structure was sometimes covered with carved stone slabs.
- Often, a pradakshina path was laid around the stupa surrounded with railings. Entrance to the path was through gateways. The railings and gateways were often decorated with sculpture.
