NASHVILLE (AP) — The Nashville radio tower for WSM that has broadcast the Grand Ole Opry since the 1930s has been added to the National Register of Historic Places.

The 808-foot tower was erected in 1932. WSM started carrying the legendary country music show in 1925 and the tower brought it to much of the South and Midwest. The live show helped popularize country music and spread it beyond the South, aiding the careers of Hank Williams Sr., Roy Acuff, Loretta Lynn and others.

The tower now sits on a 30-acre tract visible from Interstate 65 south of Nashville.

The station announced the selection in a news release Wednesday.
