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!
