The original Yankee Stadium opened in 1923 across 161st Street, nicknamed "The House That Ruth Built" because of Babe Ruth's popularity. Lou Gehrig gave the "luckiest man on the face of the earth" speech there in 1939. This stadium opened in 2009, built to echo the 1923 frieze, and Derek Jeter's generation moved over with it. The old field is now Heritage Field, a public park where Bronx kids play on the same ground. Standing between them, you can see both: the ballpark that made the team, and the one built with what it earned.
