The parisian geography is that of a plains region, marked by the Seine and Marne valleys and local heights that, without representing mountain ranges, are a good set of belvederes over the area.
Some reference points and a graphic scale to grasp the dimensions:
1- Historical core around the islands of La Cité and Saint Louis
2- Champs de Mars and Eiffel Tower
3- Champs Elysees
5- Buttes Chaumont Park
6- Versailles Gardens
7- Saint Germain-en-Laye
8- Paris- Charles de Gaulle Airport
9- Paris- Orly Airport
10- Disneyland Paris
Next post will show a personal vision on each of these spaces.
