Paris is an amazing city. It represents a unique combination of magnificent architecture, beautiful scenery, culture and people. It is the city where the history, present and the future meet together in a single place.
The new map called BatiParis is a great tool to understand how the city evolved over time. It shows age of buildings footprints in the city with each building colored according to its year of construction. You can turn on and off each period of time to visualize the major stages of the Paris development.
The map reveals that most of the buildings in Paris are from the 1851-1914 period so between the beginning of the Napoleon times, until the beginning of the First World War.
Nice project.
