  As part of the iGrid Research Demonstration at INET 2000, we created two
Virtual Cultural Heritage environments - "Virtual Harlem" and "Shared Miletus".
The purpose of these applications was to explore possibilities in using the
combination of high-speed international networks and virtual reality (VR)
displays for cultural heritage education. Our ultimate goal is to enable the
construction of tele-immersive museums and classes. In this paper we present an
overview of the infrastructure used for these applications, and some details of
their construction.
