This historical barn was donated to the Oregon Historical Society by the Jenkins Ranch. Used by pioneer cattle king Peter French for breaking saddle horses, the barn has been in use since 1884. An architectural marvel, the structure was built from native lava rock and juniper trees. Well known for its design, the barn somewhat resembles a Chinese umbrella. Twelve unusually tall juniper trees support the roof. The center pole is 35 feet high, and the roof required 50,000 shingles.
