Augmented Reality (AR) already is very interesting topic for cultural heritage since it can be very easy to reconstruct the ancient building on the site without any physical intervention. With the AR technology, 3D models of ancient buildings can be overimposed to remains of the site. In this way historical sites become more interesting and appealing places. In this study, we developed a geo-location based AR application for Roman Baths of Ankara which is placed in Turkey. Novel part of this study is using drones for video source which model of the bath will be overlaid to it.
