This is a video of San Francisco from the Marin Headlands. Here there are beautiful promontories, decaying military batteries, and amazing graffiti!
In the video I talk about the architectural concept of First, Second, and Third Nature.
First Nature is the relationship between a person and the natural environment.
Second Nature is the relationship between a person and the built environment.
Third Nature is the relationship between a person and the socially constructed environment.
Enjoy!
