The Grand Ole Opry House now has historic designation.  The Nashville venue, which has been home to the Opry since 1974, has just been added to the National Register of Historic Places, listing cultural resources worthy of preservation.  The Opry House opened on March 16, 1974 with a VIP guest list that included President Richard Nixon.  It is the Grand Ole Opry’s sixth home and only home built specifically for the Opry.  Its distinction comes as the Opry itself prepares to launch a nine-month celebration of its 90th anniversary beginning with a kick-off show on March 24th.  The Opry’s 90th Birthday Bash Weekend is scheduled for October 2nd through October 3rd.
