Fort Klamath was established in 1863, and was an important Army post during conflicts with the Klamath, Modoc, and Northern Paiute tribes.[2] The fort consisted of more than 50 buildings, including a sawmill. Four Modoc men, led by Kintpuash, were executed there in 1873 for the killing of General Edward Canby. Their graves remain at the fort.
A post office was opened in 1879. By the mid-1880s, the settlers in the area no longer needed protection, and in 1889 the decision was made to close the fort. After a harsh final winter with more than 20 feet (6 m) of snow, the troops of Company I of the 14th Infantry Regiment left the fort on June 23, 1890, and moved to Vancouver Barracks.
Fort Klamath Museum
An 8-acre (32,000 m2) parcel within the fort area is maintained as a park and museum by Klamath County, Oregon. The Fort Klamath Museum is housed in a modern structure designed after the fort's guardhouse and standing in the original guardhouse location.
