Although Portland isn't particularly known for its architecture, there are still some remarkable buildings there and lots of cute houses to oogle over while you're driving around.

I visited the Pittock Mansion and although I didn't get to go inside, the exterior was elegant and the view was amazing.
So many plants! Oregon definitely is not in a drought.
What Portland lacks in buildings it makes up for in bridges!

A short drive from Portland is the Mt. Angel library by Alvar Aalto - it's a must see if you're in the area because it's just as beautiful, peaceful, and intricately detailed as it looks in the pictures.
If walls could dream... they'd dream of exploring a new city.
