The atrium was added in 2001 and includes the Packer Pro Shop, bars and restaurants. The Hall of Fame is just below it.
I visited the Packers Hall of Fame when it was in its own building across the street from Lambeau Field but wanted to see it in its new home. Most of the information is the same but the presentation has been improved greatly. If you’re a football fan, a trip to Lambeau will be enjoyable regardless of your fan affiliation.
