Madison Township, Butler County, Ohio

West Middletown is an unincorporated community in eastern Madison Township, Butler County, Ohio, United States. It is located on the west shore of the Great Miami River about one mile from Middletown. It had about 200 people in 1905 and was formerly a station on the Cincinnati, Hamilton, and Dayton Railroad. Founded as Madison City, it received the name Heno when it was awarded a post office in 1882. Since there was already another Madison City in Ohio, the postmaster general demanded a name change. According to legend, as old-timers were discussing the new name around the cracker barrel in the general store, a can of Heno tea caught their attention. So the town was named for the tea. But in 1907, the postmaster general decreed the village was within the shadow of Middletown, and only a few postal workers had ever heard of Heno, making it difficult to sort and forward mail to the place. The government ordered the village to accept the name of West Middletown. In 1963 the postmaster general in another decree closed the West Middletown post office, transferring its business to Middletown.

The Great Mound is a massive Native American mound in the southwestern part of the U.S. state of Ohio. Located in Section 19 of Madison Township in Butler County, it has a height of 43 feet (13 m) and a circumference of 511 feet (156 m).: 224  Its total volume is nearly 825,000 cubic feet (23,400 m3),: 224  making it the largest mound in Butler County and one of the largest in southwestern Ohio. Because of the mound's height and its placement on a ridgeline, an individual at the summit can see for a great distance. In the late nineteenth century, it was theorized that mounds such as the Great Mound were built as observation or watch points, and that the builders maintained the ability to light fires atop the mounds as a method of communicating across wide distances.: 225  The potential of these mounds for long-distance communication was demonstrated in 1990 by three groups of volunteers. After climbing the Great Mound, the first group established visual contact with the Hill-Kinder Mound in Franklin (more than 11 miles (18 km) to the northeast), from which point the observers of the second group contacted the third group atop the Miamisburg Mound near Dayton.Built by the Adena culture, the Great Mound has been reduced by multiple instances of unofficial diggings. In 1879, locals removed a small portion of the mound's summit, finding artifacts such as bones and the remnants of fires. Later years saw the destruction of a more significant part of the top; today, only about 75% of the mound is free from disturbances. Nevertheless, the mound is believed to be a significant archaeological site; its size is believed to indicate the stability of the culture that built it and the dedication of its members to commemorating those buried within it. In recognition of its archaeological value, the Great Mound was listed on the National Register of Historic Places in 1971.
