Fort Riley, a U.S. Army installation located in north central Kansas, is known for many things: storied home of “The Big Red One,” early duty station of the infamous Gen. Custer, former home to two Buffalo Soldier regiments and once home of the prestigious Cavalry School in the early 20th century, just to name a few. Drive around the installation and it doesn’t take long to feel transported back in time. When you reach what is known as “main post,” the buildings transition from the standard red brick and beige concrete seen on many military installations, to native limestone, which was used for constructing the installation in the 1800s. Fort Riley’s Main Post Historic District was listed in the National Register of Historic Places in 1974, and includes 294 buildings, structures and monuments.
