Fenway Park is a baseball park located in Boston, at 4 Yawkey Way near Kenmore Square. Since 1912, it has been the home for the Boston Red Sox, the city's American League baseball team, and since 1953, its only Major League Baseball (MLB) franchise. It is the oldest ballpark in MLB. Because of its age and constrained location in Boston's dense Fenway–Kenmore neighborhood, the park has been renovated or expanded many times, resulting in quirky heterogeneous features including "The Triangle" (below), "Pesky's Pole", and the Green Monster in left field.
