The Village of Glenwillow was carved out of Solon Township and established in 1893 as a company town by Austin Powder Company. As the population in surrounding areas, particularly the city of Solon, increased, Austin Powder was unable to test its explosive products. It moved its manufacturing operations to Athens, Ohio, and closed its Glenwillow plant in 1972. In the 1980s, the village installed infrastructural and utility improvements and added a 250-acre (1.0 km2) industrial park. Served by the Solon City Schools, the village has since experienced residential development. In the early 2000s, the village received significant investment through mixed-use development, including renovation of the former Austin Powder housing stock and general store into boutiques, a tavern, in conjunction with a new town center, village park and new housing in a town plan layout.
