City Seen is a massive undertaking - a labor of love I've been developing, on and off, for years.
You'll find a lot of information here, and lots more on the way.
A few places to start:
Visit the main pages for our first four cities: San Francisco, New York, Los Angeles, and Chicago.
Use the Builders menu to learn about specific architects and builders.
Learn more about seeing, classifying, and describing buildings in our Ways of Looking at Buildings series.
Check out the site map for an overview of the site.
Browse a random selection of images at the Exploring Photos page.
We'll add more pointers soon.
