Porto: 3,000 Years in 7 Minutes

About this reconstruction

3D reconstruction built on real terrain and map data. Buildings, walls and landscapes before the modern era are approximate reconstructions; the ages of individual modern buildings are estimated from the city's historical growth, not surveyed one by one.

Where the record is incomplete or disputed, the film says so.
