The research on the maps of Jerusalem led us to 3D maps and models of Jerusalem and its main monuments. These relief maps and models were made out of paper, metal, wood and other materials. They were built in various scales and measurements from small items to large ones. The largest one was built in a scale of 1:1 in St. Louis, Missouri in 1904 and exhibited about 300 buildings including the walls and the gates of Jerusalem.
During this project information on more than a hundred models was gathered. Some of these were presented in articles. This project was carried out jointly with Prof. Haim Goren who took part in gathering the information on many of these models and in the research on the models built by Konrad Schick.
