Jantar Mantar presents the observatories through a variety of media and information sources, making it possible to explore and learn about these historic sites through interactive panoramic "VR" photographs, time lapse sequences, and 3D models as well as articles, drawings, and historic texts. It is a comprehensive resource for exploring the observatories in depth.
