The Mercedes-Benz Superdome in New Orleans. One thing I can say for sure about this place compared to any other I have been too, is that I have never seen the architecture of a building play into a sporting event so much in my life. Opened in August of 1975, the design of the dome was to help develop a home-field advantage for the hometown saints, and it has helped with just that. I visited when my favorite team the San Francisco 49ers were playing the Saints in a regular season matchup. To that day I have yet to be in a sports environment that loud, and that had so much fun together. The Superdome is unlike any other stadium I have ever been to.
