Beaver Meadows Visitor Center, also known as Rocky Mountain National Park Administration Building, is the park headquarters and principal visitors center of Rocky Mountain National Park in central northern Colorado. Completed in 1967, it was designed by Taliesin Associated Architects, and was one of the most significant commissions for that firm in the years immediately following the death of founder Frank Lloyd Wright. It was also one of the last major projects completed under the Park Service Mission 66 project. It was declared a National Historic Landmark in 2001.
