Patriots fans: What are those designs on the field outside the numbers at midfield?

Question

I'm referring to Gillette Stadium. What are those things?

Answer 1

Its a lighthouse and bridge...There is a lighthouse outside the stadium...

Answer 2

I am not a Pats fan but I helped make the stadium so I know a little of the history. It is a light house. There is a real one out in front of the stadium. Loof for it in the background shots.

Lighthouses are a symbol of the New England coast line so the Pats incorporated it in their new stadium when they built it in 2002.
