Fort Reno sits on a low rise about five miles west of El Reno. The cavalry post was active from the Indian Wars through the First World War, became a remount depot for army horses and mules, and finished its government career as a USDA research station, which it still is.
A dozen or so of the original brick and limestone buildings survive in good condition — barracks, officers' quarters, a chapel — and are open to walk around. The small museum in the old officers' quarters covers each phase of the post's history; the cemetery, with its three communities of dead (soldiers, POWs, and animals), is the place's most unusual feature. Entry is free; the visitor centre is open Wednesday through Saturday.
