Prominent Henderson businessman and civic leader John R. Arnold moved his family to this property in 1908 and added a second story to the home that already existed at the site, a house later razed in 1966. He also built a number of structures around the property, including this outhouse. Larger than most standard outhouses of its day, it had a milled pattern on the door and window facings that matched the large Arnold House. It survives as an illustration of part of the lifestyle of 19th- and early 20th-century Texans.
