The city of Bam, located at the edge of Kavir-e-Lut, 1.200 kilometers south-east of Tehran, was one of the great economic centers in Ancient Persia. The origins of Bam date back to the Achaemenid period (6th to 4th centuries BC) and the flourishing time of the city was from the 7th to 11th centuries when it was at the crossroad of ancient trade routes. It is the most characteristic sample of a walled medieval settlement erected in vernacular technique using adobe. With a surface of 200.000 square meters, the citadel of Bam (Arg-e Bam), had a 1.500 meter defensive wall, several watchtowers and all the elements of early Iranian architecture such as bazaars, mosques, schools, residential houses, government buildings, sport centers and caravanserais. On December 26, 2003, Bam was struck by a major earthquake killing about 26.200, injuring thousands and leaving more than 75.000 homeless. Approximately 70% of the buildings were destroyed. The objectives of the mission were the following: The digital restitution of the citadel and the physical reconstructions of the site and its buildings. This project emphasized on modeling two of the most important buildings of the citadel: School of Mirza Naim and Small Caravanserai. Modelling procedure consisted of four classified steps: gathering the data, analyzing and synthesizing the data, creation of the 3D model using the data analyses and preparing the 3D model as a knowledge base for the physical reconstruction of the citadel.
