Fort Harrison State Park in Lawrence on Indianapolis’s northeast side preserves part of the former Fort Benjamin Harrison, a military post established in 1904 and opened in 1906 by President Theodore Roosevelt. Named for Benjamin Harrison, the fort grew into a major training and support center for American military activity from World War I through Operation Desert Storm, and during World War II it also held a prisoner-of-war camp. Decommissioned in 1991, much of the site became a state park in 1995. Today it blends woodland recreation, trails, and wildlife with reused military buildings, museums, lodging, and other reminders of its long military past.
