Architecture of Portland, Oregon
Portland architecture includes a number of notable buildings, a wide range of styles, and a few notable pioneering architects. The scale of many projects is relatively small, as a result of the relatively small size of downtown-Portland blocks (200 feet by 200 feet) and strict height restrictions enacted to protect views of nearby Mount Hood from Portland's West Hills.
