The Remembrance Garden at Oklahoma State University-Stillwater is a serene and reflective space dedicated to honoring the lives of students, faculty, and staff who have passed away. Located on the southeast entrance to campus near the corner of Knoblock Street and University Avenue, the garden features a water fountain made from two pieces of reclaimed granite, estimated to be over 300 years old, with the phrase "Once A Cowboy, Always a Cowboy" engraved on the stone. The garden was made possible through the generosity of the estate of Murray Case Sells and was officially opened on April 30, 2022. It serves as a designated area for the Cowboy family to gather, remember, and reflect and hosts an annual Remembrance Service each April. The garden's design includes elements inspired by the original campus entrance, with a water feature, rock walls, and a bench from the Class of 1912.
