Carved granite schist blocks to build three small stupas were brought from Nepal and assembled by masons. The hollow interiors were filled with tsa tsas, set in sand. In the upper centers of the stupas various precious substances from a variety of Buddhist holy sites around the world were interred. Historically these types of stupas were often installed as votive objects surrounding larger stupas. This is a prevalent practice in the Kathmandhu valley and can be seem most dramatically at the Swayambu stupa complex.
