Check out some renderings for a Marvel Theme Park where we see "Superhero City" even has a huge Silver Surfer statue.
While just conceptual, judging from the ratio of the size of the people to the Silver Surfer, the Sentinel of the Spaceways has to be as big as Galactus by comparison!
The Marvel Theme park is currently being built in Dubai.
Note: Disney considers it an "Entertainment Center" as this was a part of some deal previous to Disney's acquisition of Marvel, and the park will include other elements as well such as dinosaurs etc. (via DisneyAndMore)
