B is the church.
D is a residence.
This is not just a residence, people: this is the Glass House by Philip Johnson. Mmm. That queen knew how to do some crazy shizzle. Behind the photographer of this shot is the Brick House, which has solid walls except for a few small circular windows. I can't even tell you how much I want to see this house, this place. I'm sure if I ever get to New Canaan, CT, I'll just fall to the ground and weep.
This is the Phoenix Public Library in Phoenix, AZ, by postmodernist and really-good-but-reputedly-kinda-vain architect Will Bruder. I had to do a project on the unusual structure of this building, and it's pretty cool. I only got a B on the project. Shoulda had Bruder present it for me. In the lecture last year, some students thought that this was the church because it looked like the megachurches you see these days.
Finally, F is a train station. It was also built before the Civil War.
St. Pancras in London, England is also a hotel. In the lecture, this was seemed to be the easiest for everyone to get as built before the Civil War because the students associate Gothic architecture with really really old buildings.
