American Inn
Portland, Oregon has done one of the best jobs at saving buildings from an early 20th Century World's Fair. Up until the 1960's 4 buildings survived. One of them, the Forestry Building, the largest log building ever built, was renovated in the early 60's but a few years later burned to the ground. The other three buildings, The American Inn, Fairmount Hotel and National Cash Register Building were moved to new locations, renovated, and are in use today.
This page is dedicated to the American Inn, in which the center part of what was a huge hotel at the Louis and Clark Centennial Exposition was taken apart and rebuilt at a new location near the downtown area of Portland.
I was able to visit it and go inside. It is condominums today and to my happy surprise the building honors the past. Above the fireplace is a picture of the World's Fair, and on the other floors several pictures adorned the hallways. Pictures of the Forestry Building and the Lobby are below.
