The Green Monster at Fenway Park stands 37 feet tall (11.3 meters) and has defined how baseball is played in Boston for over a century. Since the Red Sox opened the stadium on April 20, 1912, that brick-and-steel wall in left field became the most famous character in the house—capable of turning a single into a double or stealing a home run in the same instant.
More than just a wall
It’s a personality. The Green Monster sits just 310 feet from home plate, closer than most outfield fences in the majors. That means a 350-foot fly ball that would be a homer anywhere else bounces off the Monster and leaves the runner on second. Red Sox hitters learned to live with it; visitors learned to fear it.
Details that tell stories
In 1936, they installed the Manual Scoreboard on the Monster, a metal number board that still works exactly like it did nearly 90 years ago. Operators change every run, every strike, every out by hand. It’s a relic that fans love because in the digital age, Fenway refuses to abandon tradition. Above the wall sit 420 seats (the most expensive in the stadium) where fans watch the game from Monster height itself.
Legends who tested it
Ted Williams, the Red Sox’s legendary Splendid Splinter, hit 521 career home runs, many of them challenging the Monster. In 2004, when the Red Sox won their first World Series in 86 years, they did it at home with the Monster as a silent witness. More recently, in 2018, Boston won their fourth World Series of the 21st century, and the green wall stood there, unmoved, just as it has since Woodrow Wilson was president.
The color and the magic
The wall’s original green changed in 2003 when they repainted it a brighter shade. But the change was more than cosmetic: the Red Sox wanted the Monster to shine under the night lights, to be impossible to ignore. Today, that green is part of American baseball’s visual identity, as recognizable as the Yankees logo or the ivy at Wrigley Field.

FAQ
Why is the Monster so close compared to other outfield fences?
Fenway Park was built on a small urban lot in Boston. There wasn’t room to push the wall back, so they built it up instead. That created a unique challenge the Red Sox have leveraged for over a century.
How much do Monster seats cost?
They’re the most expensive tickets at Fenway, typically ranging from $150 to $500 depending on the opponent and time of season. But from there you get a perspective on the game that no other stadium offers.
Has anyone tried to change the Monster’s height?
Not seriously. The Monster is Fenway heritage. Modifying it would be like changing the character of the ballpark itself. The Red Sox know that wall is part of their identity and baseball history.
