Ancient Rome has been brought back to life through a unique digital reconstruction project, said to be the world's biggest computer simulation. An international team of architects, archaeologists and experts spent 10 years working on a real-time 3D model of the city called Rome Reborn. Some 7,000 buildings were scanned and reproduced using a model of the city kept at a Rome museum.
Users enter the city at the time of Constantine and see inside buildings.
The simulation takes place in AD320, which is said to be the city's peak, when it had grown to a million inhabitants.
The project will be used to carry out further research into ancient Rome's way of life and will be updated according to new archaeological discoveries.
