The Battle of Lexington State Historic Site, established in 1958, preserves the battleground of the First Battle of Lexington. It is located on the north side of town, and encompasses the Anderson House, a mansion that was caught in the middle of the fighting. Bullet holes and cannon shots remain in the walls of the house. Tours of the battlefield and walking trails are provided over its 94 acres. The site’s visitor center, to which admission is free, acts as a museum that has fascinated visitors since it was built in 1991. It features exhibits about the Anderson House, the battle itself, and Missouri’s role in the Civil War as a whole.
