Takhti-i-Bahi was listed in the UNESCO World Heritage in 1980. The site offers a glimpse of a Buddhist monastery of great historical importance and comprises the largest Buddhist remains in the ancient kingdom of Gandhara. The diversity of archaeological layers that make up the site attests to the complex history of its construction and expansion. The structures described above, as well as many other ones- and two-story secular buildings uncovered during excavation, are stone-built in the Gandharan diaper-masonry style using local or semi-dressed stone blocks with flakes, set in lime and mud mortar. The site is a great source of historical information not only for Buddhists but also for the history of Pakistan. The archaeological evidence from the site is extraordinarily rich.

And many Gandharan sculptural ruins have been excavated, including intact statues as well as fragments in unfired clay, stucco, and terracotta. Many of the images contain small sockets for fixing and supporting the bodies and heads of clay. Stucco images recovered from the site can also be seen in various European museums.

Buddhist arts and culture emerged in this region and penetrated as religion towards the far east in China, Korea, Japan, and Indonesia. As a result of our efforts invested in the promotion of Takhti-i-bhai site through presentations, it was chosen as the first series of Asia Stupa Road Digital Heritage Project in close collaboration with the Gwangju Information and Culture Industry Promotion Agency.

Firstly, it aims to explore the diversity and cohesion of Asian culture in the region. Secondly, to introduce the forgotten World Heritage Site to the wider audiences via virtual reality and immersive content experiences in the form of a virtual museum. Our team developed a virtual reality exhibition of the 3D reconstructed Takhti-i-bhai site (Figure 2). The objective was to create an in-depth sense of immersion in the virtual Takhti-i-bhai site by easy integration of 3D scenarios with head-mounted displays. This digital experience can provide an efficient virtual reconstruction environment and an air touch experience that can increase the realization of cultural heritage site experience.

These two case examples show an active role of technology in the service of cultural heritage sites. it is concluded from our practice that 3D technologies can facilitate an interactive amusement of artworks, evidence, monuments, museums, places, and landscapes. However, the trend of virtual museums is still in its early stages and a little promoted. Nevertheless, the ultimate goal should be to encourage as much as possible the 3D reconstruction of various interesting historical sites to safeguard them and to make them enjoyable by the wider audiences. In short, there is still a need to research the new 3D technologies with great ambition and competences to determine they are useful and crucial to inform and make pleasurable the history of our cultural heritage sites.
