Allianz Arena is the stadium for Bayern Munich. It's huge and really cool. On game days they light it up red but it can be programmed to be any color or lighting pattern. Inside the arena is a museum on the history of the team.
The two teams we saw play were Bayern Munich (my favorite) and Borussia Dortmund. This was a huge game with the top two teams in the Bundesliga (the German soccer league). Bayern won 6-0!
It was an awesome experience seeing my favorite team play in Germany. I got to see my favorite player, Robert Lewandowski and also a young American player who was playing for Dortmund named Christian Pulisic. This was definitely a once in a lifetime experience.
