Lumbering and shipbuilding brought the town prosperity and endowed it with some fine early architecture. This includes the Ruggles House, an exquisite Federal home that is now a museum, and the Union Church, a Greek Revivalmeeting house which since 1902 has housed the town hall, library and archives. The Washington County Railroad arrived at Columbia Falls in 1898. Tourism and harvesting blueberries are important industries today, together with producing Christmas trees and wreaths.
