The skills of our crafts persons are also apparent in the buildings that have survived, such as stupas. The word stupa means a mound. While there are several kinds of stupas, round and tall, big and small, these have certain common features. Generally, there is a small box placed at the centre or heart of the stupa. This may contain bodily remains (such as teeth, bone or ashes) 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 path, known as the pradakshina patha, was laid around the stupa. This was surrounded with railings. Entrance to the path was through gateways. Devotees walked around the stupa, in a clockwise direction, as a mark of devotion. Both railings and gateways were often decorated with sculpture.
