A stunning history of the development and preservation of the marble halls deep within the Siskiyou Mountains.

The cave was discovered by Elijah Davidson in 1874. In 1909, the Oregon Caves National Monument was dedicated and placed under the jurisdiction of the US Forest Service, and in 1922, the highway to the cave was completed. In 1923, the US Forest Service awarded the first concession contract to the Oregon Caves Company, which intended to build a hotel at the monument as soon as possible. The Chateau was completed and opened to the public in 1934 (shortly before control of the monument shifted to the National Park Service in 1936) and was designated a national historic landmark in 1987 as a significant example of rustic architecture with many original interior finishings and most of the original Monterey furniture collection intact. Outside of necessary repairs following a flood in 1964, shockingly few changes were made to the Chateau between 1934 and 1987. In 2014, the designation of the monument was changed to the Oregon Caves National Monument and Preserve, and its footprint was increased to 4,554 acres.
