Most of Glen Lyn was built recently: 7% of its homes predate 1940 and the median home dates from 1958. Below: maps from 1932 on and the census since 1930.
Mr. John Toney built the first brick house in Giles County in 1780. Toney owned the land around his settlement and named the area Montreal. Over the years a post office was established giving Montreal a new name of Mouth of East River. Railroad workers of the Norfolk and Western Railway later gave it the name Hell’s Gate. The name changed once again to its current name, Glen Lyn, meaning lovely glen, after the railroad’s completion in 1883.
During the late 1800s, a few stores and a ferry were opened, however, the community did not experience any substantial growth until the construction of the Appalachian Power plant in 1919. This development increased the population of Glen Lyn from 50 to 400 people.
