That depends on the time and place. Some ancient Indian stupas were solid on the inside, meaning that you could only circumambulate the outside. Later stupas were made to where you can walk inside and walk around a thick central pillar that contained relics. The design of the stupa changed from a large dome, to a square building with a dome top, and finally the multilayered pagoda seen in East Asia. The Japanese buried relics under the pagoda, and sometimes they would use the building to house statues. For instance, the Horyuji pagoda in Nara, Japan has five clay panoramas of the Vimalakirti Sutra, the death of the Buddha, the division of the relics, and Maitreya Buddha's paradise.
