Citi Field is the Mets' new ballpark, built just beyond the outfield fence of old Shea Stadium. It won't play host to the likes of Joe Namath and the Beatles like Shea did, but for baseball fans it's progress. Designers of Citi Field incorporated features from long-gone parks like Ebbets Field, and the atmosphere is more intimate than at Shea. In fact, continuing a trend seen at other new parks, the move means about 15,000 fewer seats. The Mets have been in Queens for more than 40 years and will remain for decades to come with this new addition to MLB ballparks.
